No, nothing is ever crystal clear because car behaviour is not a one dimensional thing. 50% of the problem is finding out if the strange things you see are the CAUSE or EFFECT of the accident.

As for your list:
Driver turns to the left for no reason: avoidance of debris or something on track? correction due to loss of grip, tyre failure? response to car failure? driver blackout?
Avoidance of debris would be shown as a correction (left-right)

Loss of grip also would be shown as a correction, and would be noticed watching more data as wheel spin, throttle position, etc.

Tyre failure would be easily shown watching suspension data, and that scenario wouldn´t be a turn to the left with no reason, but with multiple corrections to the wheel. It would also be easy to see watching the car after the crash
Tim.Wright wrote:Drop in downforce: wind? debris in wings? aero element failure? loss in downforce due to a ride height change? suspension/ride element failure or deflection?
Debris wouldn´t change downforce equally (more or less) in the front and rear end as a wind gust would.

Aero element failure is easy to see analysing the car, if they can do it with a crashed airliner analising this McLaren wich didn´t suffer mayor damage would be very easy.

Ride height change is also easy to see in telemetry.

Suspension or ride element failure would also be shown with many more sensors, for example the opposite wheel would be in the air. Also analising the car after the crash would be unquestionable
Tim.Wright wrote:Drop in battery voltage: defective battery? short circuit in H/Kers? short circuit in ignition system? blackout/brownout of the logger?
Drop in battery voltage + no driver input = electrical shock.

Drop in battery voltage + normal driver input = short circuit at some point.

If the battery is defective that´s quite easy to see after the accident
Tim.Wright wrote:No driver input: defective sensor? driver is pre-occupied with another problem? driver is distracted by radio? siezed steering?
No driver input from loose of control to the crash itself would equal to driver unconsciousness

No driver input at the exact loose of control and driver input after that would mean he could be distracted

No driver input and locking brakes would mean siezed steering, and again, would be easy to see watching the car after the accident




I´ll repeat it just in case..... I´m not saying they should publish telemetry, but with the car and the telemetry they have more than enough data to know more or less what happened. If they don´t say what happened it may be due to multiple reasons (car failure, mechanical failure due to some mechanic mistake, engine problem wich Honda don´t want to be public, marketing reasons....), but they do know what happened for sure

If only it really was that straight forward my job would be a lot easier...

What´s your job?

Anycase I never said it´s straight forward, but distinghising between a car failure or a driver blackout is. If the car didn´t fail and the driver was conscious before the impact then it will be a lot more complicated to be sure about the cause, but at least you can rule out some causes with telemetry and inspecting the car

I'm glad my angst at the impending large repair bill made you chuckle.
just to be clear, I did not find it funny that you needed to pay a lot of money in order to repair your car..
But just seeing the genuwine frustrated emotion; I could not help it, but it was funny.

added that McLaren expected Alonso to be fit to race for the Malaysian Grand Prix at the end of the month but said it was up to the 33-year-old’s doctors.

Just put him in the car PLLLEEEEASE!

wesley123 wrote:So you are just releasing half of the numbers? That doesn't give the full picture. Plus, it opens the door for everyone to say that McLaren is hiding stuff.
With the selected pieces i can easily prove or disprove the wind theory.
It opens the door LESS because you actually have something tangible to work with.
wesley123 wrote:Quite certain a press release had already explained what suspected the cause of the crash(Heavy winds)
And neither the FIA nor the GPDA believest that story so they all demanded real answers instead.
But of course, to you it´s enough, in which case this whole thread is more or less useless by now since you know the cause and Alonso is in perfect health at this time of writing.
wesley123 wrote:Except Telemetry wont show the effects and will only open the door wide for conspiracy theories.
Now you´re even contradicting yourself.
According to Mclaren (which you believe) they saw in the telemetry it was a gust of wind, they saw he ran on the astro-turf.

But now you are saying telemetry won´t show the effect. What´s it gonna be?
wesley123 wrote:It is.
For you. Not for FIA, not for GPDA, not for ex-F1 drivers, not for a large portion of this forum.
For you this is all covered already, your vicinity to this thread is by your own definitions, useless.
You got the cake and you´re eating it, no need to be in here anymore.
wesley123 wrote: No it wont. It only opens the door for everyone to back up their theories with data they know absolutely nothing about.
Yea it will. No telemetry is not rocket science like you like to believe it is.
Especially the selected telemetry pieces i proposed.
wesley123 wrote:All Telemetry will show is if something in the car itself caused the crash, which will answer nothing in the whole discussion
Sure, let´s just forget it will completely disprove the Mclaren statement first of all.
Second of all you´ll get the cause because now you really know what happened.
wesley123 wrote:because it doesn't answer, nor give any signs towards why Alonso was in the hospital for so long and misses the Australian GP.
Why are people still talking about the his days in hospital? The guy is completely fine right now, training hard for Malaysia.

Now what´s interesting is what actually caused the crash.
wesley123 wrote:only releasing a few numbers tells nothing. Imagine if doctors did such a thing, sounds pretty bad doesn't it?

Finishing races is important, but racing is more important.

Re: Alonso's Crash

I remember saying that Alonso was going to be out of the first couple of races and I did get huge ridicule for it. Nevertheless I just wanted to know if anyone else of the opinion that this whole saga is eerily reminiscent on the Nigel Mansell 1995 saga with Mclaren? i.e the car was bad, superstar driver and that vauge feeling that he wasn't all that welcome? or maybe the superstar signing has lost motivation to rebuild and develop what looks like an abortion of a car currently into something winning? Im not making conclusions, Do you get the feeling this may be Alonso's final bow?

They're/Ron not being vague. They just can't speak for Alonso's Health. Only Alonzo and his Drs can.

Personally, I think you guys are looking for problems where problems don't exist. Just based on "Alonso's Crash" it isn't hard to imagine how it all snowballed in 2008.

Being an Alonso fan myself, I also really respect everyone's passion for the sport. Please stop trying to villainize McLaren/Ron/MP4-30. It doesn't do anyone any good.

Alonso new exactly what he was getting into when he drove that car. He's paid to find limits of cars and in doing so there are risks.

I hope he is driving in Malaysia because all this tweets are rising my hopes.

Is he following Lewis Hamilton's fitness routine? He's so buff?! I've always known him a bit more skinnier.

He is also "pumped up" on that pictures, that also makes a huge difference..

When I go to fitness, afterwards I look bigger than before.. because of the blood pumped into the muscles.

Don't ever remember seeing Alonso look so big in the arms, and yes I know he's obviously going to look bigger during the exercise, it's still a staggering difference to what I remember.

I think it was your conclusion that he got electrocuted, based on his extended hospital stay, that people didn't like
Thefuelman wrote:Considering that the hospital stay has now increased to 2 days and possibly more we can say its safe to say it was an electrical shock
As for your prognostication of Alonso missing the first couple of races could be covered under "and possibly more" :D
