AI got pretty good in things they can do, but they still can't compete in Professional physics mode and that's making AI completely useless for me. Most of the races are too difficult when they all have much more grip to compete with you, they don't use the tyres you chose for your car and their back will never goes sideways. So you must compete with your NSX Type-R against Ford Focus and similar cars to be able to beat them. It's just silly system. Yesterday evening I was looking through all the races of the game for good 280HP competition for NSX Type-R, but nothing found.
