Yet, I wonder - there are so many ingenious engineers in motor sport,
but the people who design the safety features of the tracks seem to be
amateurs. Somebody in this thread said that you can't foresee all
kinds of accidents and take provisions against them - true. Senna's
crash is one example. But I think it should be pretty easy to foresee
possible trajectories which damaged, or out-of-control cars can take.
Correct me if I'm wrong, but a car that is not controllable anymore
will almost always keep going in a straight line until it is stopped,
right? And there are known parts of a track where the cars will be
very fast (f.i. at the end of long straights), and other parts where
they will be much slower (f.i. mid- to end of a tight corner).
What is maybe even more important is the angle in which a damaged car
will most likely travel in relation to the safety barriers.
Now, all a designer has to do is to calculate the most likely
trajectories and ask himself: "What do we need at this place - a
run-off zone with tire barriers at the end or a *nearby* concrete wall
which runs more or less parallel to the car's trajectory?" Both
measures, in the right places, would lessen the severity of the
impact.
I sometimes get pretty angry when I see accidents like Panis' in
Canada a few years ago, where a concrete wall without tires would have
spared his legs. OTOH, the Laguna Seca cork***is a tight corner at
the end of a very fast section. Why isn't there a run-off zone? O.k.,
so one would need to build a concrete ramp to provide one? Then make
it so! Or think about alternative restraints: how about the nets that
are used on aircraft carriers to catch planes which cannot use the
hook? If it can stand an F 15, it surely can stand a champ car.
I could go on forever just citing examples from this year. What about
the accident by da Matto (sp?) a few weeks ago: what the heck was the
hole in the barrier doing at this place? Just where a car will go when
the driver loses it accelerating from the corner?
Racing is dangerous and will always be. Vehicles moving at more than
300 km/h in an environment with solid obstacles will never be
completely safe, unless we develop UFO-like force field technology. ;)
But I don't think that everything is being done to make racing safer,
even with today's technology.
Sorry for ranting. :)
ObRAS: Despite Rodriguez' death, I watched and enjoyed (moderately -
this week's F1 race was more exciting, for a change) the Laguna Seca
race. More than ever, I feel we need a competent new CART sim,
preferably by Papyrus and using the GPL game engine. I had to fire up
ICR2 again to drive a bit on this track - I can live with the
graphics, the model of the track is still excellent, but the physics
are definitely outdated by now.
