The main one seems to be deformable structures that cushion the blow. On the long public part of the Le Mans track, that would be a fundamental, non-traditional and expensive implementation. But if the speculation about the cause is correct, I'd expect to see a few strategically placed walls of tyres at a few identified spots around the track - representing learning and improvement for 2014.
I agree with you Rinehart, and my comment wasn't meant to say "well that's just life, nothing we can do about", it was in relation to the rally car crash and it's consequences.
While this crash was survivable for one person, it wasn't for the other - where to we "draw the line", in terms of limits (deceleration etc.).
Even with the best intent and effort, you/we will never be able to account for all variables and circumstances, a bit different angle, could have made all the difference, and the guy would have walked a way from it, as many other did.
I'm sure that ACO and others will look at this, and take the lessons learned on board, and that is how it should be. I didn't mean to say, that nothing can/should be done about it. But at the same time, we shouldn't think, that we can prevent all serious consequences from happening. It's still a dangerous sport, and the people participating in it, are aware of it, and accept it as part of the challenge.
And it is the challenge, that makes up part of the legacy/legend of Le Mans, Spa, Nürburgring and other places.
Some people still go onto a bike, and participate in the TT, even so, that they know that it is a pretty dangerous race/place.
But there is satisfaction in mastering a difficult task, and this motivates/drives some people to do it, they want to master the challenge.
And to me this is a right, which everyone should be able to exercise for himself, if he choses to do so. If we talk about public transport etc. , that's a different matter.
Being it racing in Le Mans, Dakar or other places or jumping with a parachute from the fringes of space.
As for possible improvements to the track.
We have seen the car coming back across the track after the impact, the likelihood of this happening would increase with a tyre barrier, so it's not such a straight forward argument - IMO.
A car spinning back across the track, especially at night, and being hit by another car on the driver side etc. has it's dangers too.
I'm not qualified to make a assessment of all the pro and cons, but I'm sure other people are, and that there input will be taken into consideration, so that a good overall compromise can be found.
In parting, maybe we should leave this threat as a place to bid our farewell to Allan, and move the rest of the discussion to another thread.
It's a valid argument and could/should be discussed, but maybe this is not the best/right place to do so.
R.I.P. - Allan & thank you for the memories
