This weekend we had a BT20 league event at historic Francorchamps, and even tough everybody was well trained and well behaved, the races were ruined by chain collisions. Most of those were caused by an initial car going off and then the 'crash physics' causing a pinball like mayhem. How come crashing at 300kph onto a wall or barb wire fence will make the car bounce back so much? I might be naive here but maybe the fences and chassis of the car could have their 'coefficient of restitution' adjusted to be close to 0.0. Then if the wheels separate early enough in the impact simulation and the timestep/frequency is sufficient, they would bounce all over the place but the chassis would 'smash and slide' instead of 'smash and bounce'
It's very hard to tip drivers out as well. In NASCAR a slight tap on the rear quarter panel will send someone off and a gentle push in a touring car will put them in one of those PIT moves you see on Police Cop Death Chases or whatever. Yet when the AI does it to you, you're off.
Agree with you, but despite it's 2018 and there are so many things to implement, i guess we can only hope for realistic crashes/deformations around 2030...
