I have Forza and having damage is good and bad. Its good cause it means you have to actually try and get past instead of just stragically hitting the car in front, do that in Forza and you'll just bust your steering. But the bad things is that the AI has been programmed with the principle of racing room, so outbraking another car will often end up with them taking you out. Also often the ABS comes on when you only just touch a brake, even in the P1 class cars
