I know that there are hundreds of threads littering the boards with numerous ideas on how to improve overtaking etc., etc. Maybe I'm being naive and or ignorant but I find it difficult to fathom that we have so many ideas from so many personalities in F1 on how to get this done and NO RESULTS.
Paddy Lowe went as far as suggesting that it's not the cars that need changing bur rather the tracks. http://news.bbc.co.uk/sport1/hi/motorsp ... 307309.stm
Then there are ideas about brake disk compounds and various gimiks suggested by different F1 personas.
I can only speak from the limited racing experience that I have, that when there is a large disproportion in relative terms between engine power and mechanical grip, you have overtaking. The idea being that it's that much harder to bang out consistent lap times. There is a greater mistake factor and also greater potential when all goes right. Greater uncertainty, greater tire management skill required etc.
One guy gets the exit right before a straight, and the other doesn't and there you have a classic pass into the following corner. The guy that got the turn right and got a good grippy run out the corner is going to use significantly more of the available engine power down the straight than the guy that didn't. That's a pass. Who knows maybe on the next lap it's the other way around and you may see a battle. (Wow those are a thing of the past).
All these "difficulties" and inability and ideas in F1 make me really wonder. I know I'm sounding arrogant, but it can't be that difficult to understand why passing happends especialy for the drivers and sport insiders.
Passing has gone, because they have taken engine power away from the drivers and have provided relatively balanced aero and mechanical grip levels with the apex speeds going through the roof! Sure when the car is glued to the pavement and there is less room for error you won't have passing. Where as before the drivers had numerous areas of improvement somehow we now have drivers saying "I ran a perfect lap".
One example I can suggest is dirt racing in whatever form. Lots of power and no grip and hundreds of passes. I don't think the recipe changes for F1.
Put more responsibility for a perfect lap in the hands of the driver and less in the hands of the car and you will have passing.
Another way to look at it, is that "the edge" is really thin. I just got one of those toy racing sets for my nephew. The ones where the cars are on a magnetic rail, and there are two tracks. I see current F1 very similar to that. Up to a certain speed, the car will remain on track, but if you exceed by just a little bit it goes off flying; all because the car is glued to the track and limits the driver factor. This leaves no room for small mistakes that lead to passing and instead lead to relatively violent offs.
More power + less grip = classic passing.
