I don't like unique train of AI cars with random performances as in AMS 2. In AMS 1 there is a system of performances of AI cars with talent files of single car.
Unfortunately this is another thing inherited from the Project CARS base. This was also a MAJOR reason I didn’t get much longevity out of Project CARS so I really hope Reiza have some plans to make this editable or, at the very least, tie drivers to specific cars.
