I know there was a lot of discussion about that point, but for me this is the most important next step.

Things to improve (on my opinion):
- flipping over of some cars, e.g. the XFG flipps too fast
- collusion detection and impulses after collusions
- mechanical grip of the tyres e.g. the spinning on the FO8 in 4th gear

Yeah, and steam for an overheating engine. Perhaps with cooling water on the track ...........
