Re: Improving the ability of F1 cars to overtake ontrack

Post

There's an interview of Sebastien bourdais in the french version of F1-live.com

where he gives an interesting fact:

The F1 cars have lots of downforce, low tyre grip and then the cars are harder to drive but bourdais finds it is much more fun like that since every error is paid a lot, so considering next year the downforce will be decreased by 50% isn't here an interesting debate?

Well, as "Le Seb" has

experience of both F1 and ChampCars, I thought it'd be beneficial to also add an engineer's view from a person that shares that perspective. Toyota Racing Development's (TRD USA) Pete Spence's (VP & Tech. Director) musings over IRL/ChampCar's future are more or less directly applicable to F1 as well, at least when it comes to overtaking I think. Having worked with Cosworth and Senna at McLaren in F1 he came over to work in Cossie's CART program and has since acquired experience of IRL and NASCAR as well. The whole G. Kirby article is class, as usual ("There's a lot of junk out there today. If you want it straight, read Kirby." -- Paul Newman), I'm just quoting the directly applicable parts here.
Gordon Kirby, in an interview with Pete Spence wrote:We learned in the CART series that the horsepower and drag and downforce all need to stay in balance. Downforce changes the character of the racing. Early on when I was in the CART series, I thought the way forward was to take downforce away because that would bring skill back into it and then we would see more interesting racing. But the thing we learned is, that's not the case.

It was really interesting racing back when it was Michael versus Al Jr. In those days they had gobs of horsepower and thousands of pounds of downforce and were diving down the inside each other going into turn one at Milwaukee. They could outbrake each other and they had the confidence to go down the inside.

Take away the downforce and you take away the driver's confidence and you get a procession. Keeping the power, grip and downforce in balance is the key because inevitably, the performance goes up, the grip goes up, and the downforce goes up. So you have to either start adding drag, or take away engine capacity, and of course you're always under pressure not to change too much because it's expensive.

...


The challenge is to continue the balance relative to the human being. So many of the open-wheel performance parameters have advanced so much relative to the capabilities of a human being, I think the challenge there is to maintain a level of technology which makes the vehicles interesting to the fans while inhibiting the development such that the balance of the performance of the vehicle versus the driver's ability to control it and the driver's confidence all stays in balance so that people can still pull out to pass or use their skill to go faster than the next guy. At the end of the day, we're here to see a race between human beings.
I'm not sure if I'm willing to accept all that he says (he mentions the human/driver element as the "weakest link", to which I have at least philosophical objections), but this comes from a person who has been intimately involved with all kinds of top of the line open wheel racing series for a long time. I find it interesting that more and more people seem to be giving serious thought to this issue at this point of time. Not before long, it will also mean solutions emerging, some of which may or may not be complementary to each other.

This makes using Hybrids and KERS systems seem like the obvious next step then. If the technology is human centered, and needs to be kept balanced, then the only logical assumption is to retire overly-mature technology and introduce new tech that is still within its human controllable infantcy.

Re: Improving the ability of F1 cars to overtake ontrack

Let's back up a second. Think of the high level before getting down to sillyness like saying tires should lay down magic grip juice that evaporates in seconds, or to throw this idea at the problem or that.

What leads to an overtake? One of generally two things - Either Car A has more grip capacity or speed than Car B.. or Driver A can just get more out of the situation.

With a really spec series, the first situation is not possible. Opening up technical development does allow for differences between cars. This is good if the situation is such that say, the Ferrari is better on corners and the Renault is clearly better on straights, and you have that style trade off. However, this can also lead to just spreading the field wider.. where you have say a McLaren that is so outrageously developed that it absolutely blows a Toyota out of the water. Or likewise if one team can spend $400 million on development per year compared to $40 million for another. That's a big difference especially when it comes to hardware and analysts for CFD and vehicle simulation.

Driver aids make overtaking difficult and take away an element of driver skill. If going through a turn there is an optimal amount of throttle modulation and power to put down and every car on the field can take it flat out without thinking, there is zero opportunity to overtake. Part of this also plays into aero, in that with massive downforce and aero efficiency more of the track becomes power limited rather than traction limited.

The spirit of Formula 1, I feel is to be a pinnacle of motorsport. An area rich in engineering, in development, and incredible driving. I see it as a big emphasis on spirit and on the brain, be it of the engineer or the driver. Shouldn't be about the dollar.

No one wants to see a spec series, nor is that the way to go. But it would be nice to level things out and make the series more open for new or smaller constructors so it isn't just a game of who can outspend who, and if it will be a Ferrari, McLaren, or Renault year.

Things I feel will make it a better sport, either individually or grouped [I havent read the regs closely lately, some of these are coming in the pipe or are already in]
  • No traction or launch control
  • Some aero reduction, but not much. Maybe not all turns then can be taken flat out. Plus I like the look of "clean" bodywork rather than loaded with flip-ups, chimneys, and things that make the cars look like samurai rather than racecars. Take away lots of downforce though and you really solve nothing. The cars won't be stable or limit machines. Someone in an earlier post had a good quote about this. It's about BALANCE.
  • Limits on testing. You may laugh, but maybe take an idea from Nascar. Reduce and track the number of tires available for open testing. Nascar did this to try to level the playing field since the very well funded teams could test all they wanted while smaller teams got screwed on test miles
  • Cap salaries, not technology. No idea how to enforce it, but put a hard limit on expenditure, not necessarily what its spent on. Encourage creativity. Instead of saying "Ok you can't use active suspension", say "Ok we're opening some more technology up, turbos, active suspension.. here's $100 million dollars for the year, see what you can come up with"
Things that I don't think will contribute much..
  • Slick tires. Though I really want to see them anyway and will improve vehicle handling, I dont see how this would improve overtaking.
  • "Green" technology. Biofuel and energy regeneration systems.. I'm sorry but the technology between race and passenger market does NOT translate.. or at least very rarely. Plus I don't see how it makes the sport any more interesting.
  • Engine freezes. Great way to just lock in any sort of disparity or ridiculous advantage between engine manufacturers if there is one. Again, just saying "ok no engine changes" doesn't reduce cost. Those extra millions will just go to more CFD or damper tuning time or vehicle modeling or what have you.
It's late, I'm going to bed, hopefully some of the above makes sense.

By the way, if you think top series racing drivers are in it for the money and are too afraid to overtake.. that's a stretch. Racing is outrageously expensive, particularly in the lower levels. You don't just plop your butt down in an F1 car. If you attempt to get into professional motorsports there's a much better chance of bleeding heaps of money than making any. You do it because its fun (the weekend autocrosser), because it is a driving passion and its what you are born to do (Senna), or from a business standpoint to try to make some amount of money.

By the way, it takes a LOT of balls to pull crazy overtaking maneuvers. I don't know how many have you have been in any sort of high power-to-weight open wheel cars. It's an insane experience. It's as good as sex. But it is TOUGH at high speed and the limit of your reflexes to really take in the situation and make a brilliant move. Particularly a smart one. Takes some serious balls to say "yea I'm gonna lock 'em up here to outbrake this guy and skip over this kerb for the overtake" when you have the chance of losing it all, at 150+mph. Hell, by the time you even have that thought the opportunity is already gone! :)
Grip is a four letter word. All opinions are my own and not those of current or previous employers.

Re: Improving the ability of F1 cars to overtake ontrack

Post

Hhhmmmmm...... some very interesting posts here, Ciro Pabón's video shows us everything we have lost. Personally if you look back, for me, the best racing was achieved when budgets were much lower and overtaking was possible through slip streaming, out braking, taking a better line or by looking after the car so that its engine, brakes and/or tyres were in a better condition at the end of the race, allowing a driver to drive past the cars of those who had not taken care of their cars.

Today's racing is not about looking after the car and tyres, except in extremes of weather or changeable conditions, which is when we see lots of real overtaking; its about driving every lap like a qualifying lap. If you get stuck behind a slower car/driver combination you are shafted. While we still see overtaking on the track, the majority of it is done with pit stop strategies, which is definitely challenging but leaves me feeling a little cheated. To improve overtaking and the spectacle of F1 we need to;

reduce the dependence of all the aerodynamic add ons who's performance is so badly effected when following another car, this could be simply achieved with a standardised ground effect underbody and a ban on all appendages;

introduce tyres that do not leave marbles all over the track so that alternative lines are still possible throughout the race;

life the tyres so that they will last 1/3 or 1/2 of the race if they are looked after, introducing another driver skill. Alternatively give them three sets to last the season, including testing;

look at increasing braking distances by returning to a more conventional set-up with iron disks and a pad set-up that lasts much longer than a single race. two sets of discs and four sets of pads for the season, including testing, would see to that and bring the technology closer to that of our road cars;

finally, F1's expenditure is so high that its throwaway habits are obscene and certainly not green or relevant to today's motor industry. Imposing massive life increases on all components and even standardising some components to limit spending would bring this under control.

Please don't get me wrong I love the technology and innovation that F1 inspires but for me F1 must return to its roots as a "Drivers" championship because as it stands today it doesn't matter how good the driver is if his car isn't in the top 2 or 3 he has very little chance of fighting for the championship and even for points in a lot of cases. Is it any wonder that the top teams, with the exception of Toyota, have the biggest budgets?

It is possible even with a spec series. The problem is that "spec series" means that you have the same baseline car, not the same car, else it would be a driver series with no teams.
So, in the first place there're set up differences that make performance sufficiently spread so that you have 2 seconds difference in a play field for a series like CCWS; But also driving technique is about having more grip.

While i see what you mean, i stress that even if everybody had the same car (same set up too) the situation were someone via driving technique would have more grip through a turn is totally possible.


Driver aids make overtaking difficult and take away an element of driver skill. If going through a turn there is an optimal amount of throttle modulation and power to put down and every car on the field can take it flat out without thinking, there is zero opportunity to overtake. Part of this also plays into aero, in that with massive downforce and aero efficiency more of the track becomes power limited rather than traction limited.
Drivers aid don't make overtaking difficult, sometimes it can be just the inverse like in the rain were TC allowed for turn out overtakes.
Also i think this idea of F1 cars now being able to go flat out through turns is not correct.

First of all the "flat out" statement is misleading, "flat" means floored gaz pedal,it doesn't mean "max speed".
while 2000's V10 cars did not take spa's "pouhon" turn flat out (or Silverstone's "copse") it was simply because the entry speed was higher than with V8.
To tell the truth some turns were taken faster in 2004 than those recent years.

Next, "flat" turns that are new are rare you still need to brake a lot.

No one wants to see a spec series, nor is that the way to go. But it would be nice to level things out and make the series more open for new or smaller constructors so it isn't just a game of who can outspend who, and if it will be a Ferrari, McLaren, or Renault year.
The problem IMHO is not in the fact F1 is an open developpement but just that it is an open budget series, that's different.

And to tell the truth Champ car was maybe a spec series but budget wise it was open so no wonder why newman haas was in the front and some other always in the back, 2 seconds slower.


[*]Some aero reduction, but not much. Maybe not all turns then can be taken flat out.

Take away lots of downforce though and you really solve nothing. The cars won't be stable or limit machines. Someone in an earlier post had a good quote about this. It's about BALANCE.
The aero reduction is a difficult topic, you can't oppose tyre grip to aero grip since tyre grip multiplies aero grip, so you have to make a huge cut into aero.
Basically what you do is to balance either towards more tyre grip or more aero grip.
for 2009 the overall grip will be reduced (cars will be slower) and it will be more mechanical grip, this is a first step measure, as aero grip will come again in 2011 under another form, with adaptive aeros.

so for 2009 more mechanical grip and confirming what sebastian bourdais said, the slicks F1 cars are more predictable.
[*]Cap salaries, not technology. No idea how to enforce it, but put a hard limit on expenditure, not necessarily what its spent on. Encourage creativity. Instead of saying "Ok you can't use active suspension", say "Ok we're opening some more technology up, turbos, active suspension.. here's $100 million dollars for the year, see what you can come up with"
This is planned for 2009.




I think your remarks on the "balls" are true, but i'm confident the actual drivers are like that( men and women included).

This is still the same today, it simply occurs faster and is harder to notice.
There's not 150 ways of overtaking.
its about driving every lap like a qualifying lap
This is very true and fundamental sporting problem.
F1 cars nowadays lap just about 2 seconds slower in race compared to qualifying while 15 years back they lapped 8 to 10 seconds.

reduce the dependence of all the aerodynamic add ons who's performance is so badly effected when following another car, this could be simply achieved with a standardised ground effect underbody and a ban on all appendages;
Standardizing that part of the racing (which is super important) is just the wrong thing to do and i do hope the FIA won't succeed in doing that for 2011 (because this is planned).

Even the engine freeze is better managed since it is not a standardization and let each team tune its engine.

Wings does have a lot of benefit especially considering the drag reduction and stabilizing effects, and also it is interesting to have them varying their efficiency with condition, this just make driving fun.
It needed to have less sensitive aero yes but a slight loss of downforce when following someone is necessary.
Aren't we talking about F1? a series supposed to be with the best drivers?
introduce tyres that do not leave marbles all over the track so that alternative lines are still possible throughout the race;
I think the same than aeros, yes you're right it is necessary to have less marbles, but also not paving the way completely.

I disagree here, there's a misconception that shorter braking distances prevent overtaking.
This is not true, shorter distance require to be more precise (but we're in F1 right) but certainly have their effect for example enable for later straight line overtakings, better out braking, and as everything with speed, magnify you're braking and line stealing skills.

Also "out braking" doesn't mean braking better, but stealing a line.
You don't need to brake better to overtake someone on braking.

We are talking about a DRIVERS series which is why we must provide a framework of aerodynamic rules that allow cars to follow one another more closely, something the current regulations have made more and more difficult.

Jersey Tom,

I suggest playing Gran Turismo 4 on the PS2 with the Logitech G25 wheel setup. I know it is not the best sim going, but you cannot doubt the utter thrill and anxiety of the Toyota Minolta 88V-something on the Nordschleif, locking them up at 250mph to make the last hairpin before the carousel.

1223bhp, and let me tell ya, after a few laps, you get into the groove, and are using the curbs as pivots by putting your front tyre over it, letting it rotate the car just far enough to put the power back down, or my favorite is my buddies way of getting the outside rear tyre in the grass, just to over rotate the car to slide it under power through a few complexes.

That car is utterly crazy to drive, but when you were talking about driving the tough overpowered car, it immediately brought that to mind!

Thanks for letting me diverge,

Chris

First, i think you're misleaded on F1, F1 is both an engineering (constructor) and driver championship.

Then, what standardizing as to do with overtaking? nothing. In you example what would ease overtaking are the underfloor, not the fact they'd be standard.


Firstly, shorter braking distances do reduce the opportunity to overtake, something we are trying to increase;
Stating that is not sufficient, you have to bring arguments.
Secondly, out braking does indeed require better and smarter braking and yes part of this is car positioning that leads to stealing a line, but if you can't get along side you aren't going to steal anybody's line;
That's not correct, the "out brake move" implies braking later BUT going deeper into the turn (that's finishing your braking later), you simply steal the inside line and your job is to get back on throttle soon to avoid a "switch back".
Real occurrences of shorter braking are rare.
Thirdly what relevance do carbon carbon brakes, 6G braking deceleration and replacing discs and pads every race have with the cars we drive, let alone the cost?
??? because you think steel brakes on champ cars are kept for several races? and you think they're affordable? they bring at least 3G of deceleration, what's the use then?

Are you aware that more and more sports cars are fitted with carbon brakes now?

You're comparing apples and oranges, the performance of the brakes can't be judged on the relevance side, if you do that then nothing in sports cars has a relevance from tires to gearboxes.

Re: Improving the ability of F1 cars to overtake ontrack

1. I have been an avid F1 fan for many years and am well aware that there is a Driver's championship and a Constructor's championship. As an engineer I am constantly amazed and fascinated by the technological progress being made each and every year. The real problem is one of balance between both championships and at present, with the current rules, it is more heavily biased towards the ability of the constructor than the ability of the driver. Hence the need to change rules to redress the imbalance.

2. A standardised ground effect underfloor within a tight framework of aerodynamic rules that limit overbody appendages that generate downforce would reduce the impact of following the car in front, allowing the car behind to follow more closely and giving the driver a better opportunity to take advantage of the lead car's slipstream. This is because downforce generated from a ground effect underfloor is reduced much less when following another car than the downforce generated under the current rules. By standardising the underbody it provides all the teams a stable base to build on and gives the governing body an effective tool to limit and control overall downforce. It also reduces costs as it limits development in this area, but there will be other areas were aerodynamic development can and will occur.

3. Longer braking distances also increase the amount of time to complete the manoeuvre. Because of the increase in distance and time there is an equivalent increase in the window of opportunity in which to carry out an outbraking manoeuvre. Increasing the size of this window will increase the frequency of its use and hence "Improving the ability of F1 cars to overtake ontrack", which if you hadn't noticed is the subject of this thread.

4. The nuances’ of the outbraking manoeuvre can be debated else where. As a former racer I can tell you its about timing and having enough feel to balance the brake peddle on the maximum available grip. This skill can vary quite significantly between drivers unfortunately you don't see it very often with the ultra short braking distances we have today. However when the weather conditions play a hand, in increasing the overall braking distance, then you can clearly see these differences.

5. Yes more and more sports cars are fitted with composite brakes, which tend to have a high ceramic content to give them a reasonable working life. However they are extremely expensive and represent a tiny, tiny proportion of cars on the road today. Steel brakes "whats the use then?" firstly, see point 3 and the title of this thread; secondly, if the teams are limited as I proposed earlier it would, despite an initial increase in cost to implement the change, provide a major long term reduction in cost. We will still see high G deceleration rates, yes slightly lower, but with slightly longer braking distances and substantially cheaper costs.

That has been always the case and this is the proper of a manufacturer series.
The purpose of the constructor is the innovations, and innovations give advantages to drivers.
If you want to see drivers at more at level field watch a specs series. Teams can develop their set up but that stays balanced.
2. A standardised ground effect underfloor within a tight framework of aerodynamic rules that limit overbody appendages that generate downforce would reduce the impact of following the car in front, allowing the car behind to follow more closely and giving the driver a better opportunity to take advantage of the lead car's slipstream.

It also reduces costs as it limits development in this area, but there will be other areas were aerodynamic development can and will occur.
Yes you're right, but again we're not in a spec series and considering the sole aerodynamic problem, it can be solved by defining some shapes constrains or via flow proprieties measurements. No need to standardize things while this is of course far easier, this is F1 not GP2.
3. Longer braking distances also increase the amount of time to complete the manoeuvre.

The problem with that kind of discussions is that only one side is treated.
Of course shortening distance shortens the time to make the manoeuver...but it also shortens the time for the overtaken car to regain the same braking efficiency (if we go according to you that outbraking manoeuvers are better braking ones), it also provide in a shorter time the greater deceleration differential, it provides with the possibility, in case of deep braking, of faster re-acceleration and more importantly it provides more opportunities to overtake before the braking zone by slipsteaming (the hakkinen on schumacher with zonta being the most evident example of that).

So as you see this is many sided, and the same goes for the overall pace of F1.

One thing for sure, since the reaction time of pilot is almost fixed it make the decision process harder, but physically this is not the case.
4. The nuances’ of the outbraking manoeuvre can be debated else where. As a former racer I can tell you its about timing and having enough feel to balance the brake peddle on the maximum available grip. This skill can vary quite significantly between drivers unfortunately you don't see it very often with the ultra short braking distances we have today. However when the weather conditions play a hand, in increasing the overall braking distance, then you can clearly see these differences.
Thank you, while on a very low level karting, i think i can also be considered a driver, and hopefully some greater level drivers share my view that it is a question of timing yes.

For sure if you brake better you can overtake, but that's not necessary.

The ultra short braking distance don't hide outbraking, it often emphasizes them as the reaction time being fixed, any driver that decides to break a bit later or too soon ends up too slow or too deep.
So many examples of that in recent years, the image coming to my mind being the ultra seen too late braking where the car goes straight in the turn.
5. Yes more and more sports cars are fitted with composite brakes, which tend to have a high ceramic content to give them a reasonable working life. However they are extremely expensive and represent a tiny, tiny proportion of cars on the road today. Steel brakes "whats the use then?" firstly, see point 3 and the title of this thread; secondly, if the teams are limited as I proposed earlier it would, despite an initial increase in cost to implement the change, provide a major long term reduction in cost. We will still see high G deceleration rates, yes slightly lower, but with slightly longer braking distances and substantially cheaper costs.
I don't agree with the point 3 while i agree with what you say here, i don't think it is necessary. Certainly carbon brake are more expensive but far from being the most expensive devices of F1.

A budget cap is on track for 2009 so let's see where the teams will change that.

As far as overtaking is concerned, to sum up my post, i don't agree at all on the braking zones, and while totally agreeing that a reform has to be done (and is already done, for 2009 and plans for more in 2011 and 2013) the standardisation and underfloor are not the good solutions, while being the easiest yes as your said.

But again we're in F1, and "simple yet effective" solution, that are conservative are imho not the purpose of f1.

Because, yes, you can do a near F1 perf car, that is called a Dp01 of champ car, slick tyres, GE downforce, Turbo and steel brakes...predictable car(tyre grip big, downforce moderate) with understeery nature (ground effects car), not so nervous (no carbon chassis and bodywork so more weight) with bigger braking zone which resulted in overtakings being made with the push to pass button and almost no overtaking during corner because the car were not responsive enough.

You can have that for 20M a year.

I prefer an A1 car, underpowered but at least the speeds are according to the tracks and the aerodynamic package is done well to ensure close racing.

But still that doesn't come near F1.

Musashi San,

I guess we are going to have to agree to disagree. Over the years F1 has become more and more professional, which is a positive thing, unfortunately it has become less of a sport of men and more the battle ground of manufactures and obscene budgets.

Yes on track overtaking manoeuvres do happen, the problem is that they are increasingly rare and the sport is much worse for it. It is increasingly difficult for drivers to show their skills and race craft as the rules stand today; and while the cream will always rise we will not see the next young Senna or Schumacher upsetting the established drivers of their day by out driving them in lower order cars. Now before you start saying Lewis Hamilton did this last year I would point out that he was arguably the most well prepared driver ever to enter the sport and did so in one of the best cars on the grid.

So far all you have done is argue against improving the ability of F1 cars to overtake on track and you appear to want F1 to continue its current unsustainable course.

My question / challenge to you Musashi San is to detail what changes would you make to improve overtaking and the F1 spectacle?

This is where a topic turns into sad when because i don't agree with you on some points you draw conclusion like that.

If you're not open to discuss in details and want only people to agree with you, it was not needed to answer me.

I discussed many technical propositions you gave as solutions to the overtaking problem in F1, stating that the one your proposed were not meaning of better overtaking and all you conclude is that i argued against overtaking improvement.

"Throw it all" is so much the motto of many people on F1 forums.

Like those "ban the aeros! bring back mechanical grip! Cars are on rails!" or "bring back mechanical gearboxes!"

The opinions in themselves are valuable but so many people throw them like that without arguments.

I'm not there to act like that, if you have ideas and feel people are wrong, discuss them.
My question / challenge to you Musashi San is to detail what changes would you make to improve overtaking and the F1 spectacle?
The aero debate is already tackled by the OWG, we need to control the turbulence by design and measurements and make less sensible aero surfaces.
This is already in place for 2009 in addition with a slowing down of cars that will "bring back the mechancial grip".

Mind you, schumacher expressed his doubts that it would produce better racing, and i do too since the large aerodynamic grip propotions in F1 make the driving far less predictable and fare more sensible so both errors and skill required are high.

But the OWg couldn't tackle such a subject in one year, that why in 2011 , adaptive aero will bring more downforce on the low to medium speed while limiting the max aero downforce (even if it is planned that the max downforce will be increased in comparison with 2009).

In 2011 an underfloor standard is planned, i don't agree with that plan as i think we could totally make wings sufficiently efficient without having too much turbulence (a good combination of diffuser+wings is sufficient).

But all in one, mathematically, physically the OWG is on track.

Traction control and engine braking are not there anymore, that's good.

Now sporting regulation have too change, more reward in taking places (and first and foremost, winning) is necessary as now there's no real advantage of risking a shunt to win if you only take 2 more points than the second; consistency has won.

Finally speed is a good thing, it makes driving difficult and magnifies errors and good driving, that's why you're seeing overtaking in nascar and irl.

So here you have my views.

Amen, Nick. We missed you.

Ogami, you missed Nick point, I think.

The widely known suggestions are to improve tracks, diminish downforce, cap budgets.

Anyway, I think Nick is pointing to the fact that F1 has become since 2000 (sigh) the "ugly cousin". You love it because you have to, but it's quickly becoming the ridicule of the racing world. No NASCAR bashing can hide the fact that Champcar, Indycar or NASCAR are entertaining and have fans that know the sport and, heck, they maybe even race on a weekend or tinker with their cars.

F1 races are boring, let's be frank. No amount of tinkering with the rules will change the fact that F1 is addicted to downforce. I won't post more graphics showing how overtaking hasn't changed in years: we all have fall asleep watching the races, haven't we? Besides, the stupid "pinnacle" proclamation... well, I don't know what to say about that, except that pride goes before the fall.

There is no surprise in the results: you can watch curve number one, go to the movies and come back, the cars are in the same order. We could as well watch only the qualy.

Any driver that "goes off the official line" is expelled or sunken in an inferior team. Actually, it's even harder for newcomers to get a fine car: there is a larger danger of being expelled from a post in the government than of losing an F1 seat at major teams. It seems Massa will remain at Ferrari until he retires because of old age. How could it be otherwise? You cannot beat the guy in a Red Bull (well, maybe once in a blue mooon).

With all due respect to the posts of our friends here, if you want to know what's been doing about overtaking in real life, why don't you check the "Overtaking Group" website and feed us back?

I repeat loud and clear: the odds of anyone of us finding a "solution" to a sport that's becoming boring to the bone are infinitesimally small. No make-up will make your cousin look better (well, maybe a little, but you know how your cousin looks when she overdo the make-up). :D

Finally, I don't know what's happenning with this site. One more thread about what's wrong with F1, the pecking order of drivers, the endless bickering about who cheated or how to mod a car and I'm going to faint. ;)

Sorry for complaining in this thread, that has been moderately entertaining, but I have not the guts to participate in any other of the ones I see in the main page.

Ciro you've hit the nail on the head :wink: What is guaranteed makes your cousin look better :?: ....



....beer goggles :lol:

So lets add a couple of litres of beer to the drivers pre-race hydration program and sit back and watch :wink: Can you imagine the post race interviews, we'd certainly understand what the drivers really thought rather than what their team's PR people told them to say :lol: :lol: :lol: :lol: :lol:
