Although having said that, having things like glass or bodywork that can cause punctures or damage to your car would be pretty neat.
When was the last time you saw a real racing car get a puncture from broken glass then? The only piece of glass on any modern racing car is usually the windscreen and that'll be laminated/toughened.
The damage model is now good enough to be going on with I think. The key thing is that there's a penalty for crashing, getting it to be realistic would require far more detailed car models than we currently have. Racing Legends come to mind...
Sounds engine & graphics engine will be great from a cosmetic point of view but the new tyre model is the only thing which has the ability to make a step change to the sim as it opens up enormous possibilities for variable grip under different conditions. Grip build up, proper transitions to night, even better FF, marbles etc.
