That's what I thought but I saw in the livery overrides folder a listing for formula rookie and I was wondering if that is a separate designation. As you can see, I was working on a formula trainer skin yesterday which drew my attention to the formula_rookie folder.
There was a Formula Rookie in PC2, which was basically the same as the Formula Trainer is in AMS2. Maybe it's a leftover, but might also be something new coming in the future.
Keep in mind current main release has the rear tyres overheating, due a bug. So it will feel weird, but still somewhat driveable. Very slidey, tho.
I certainly agree - I find it very difficult to keep up with the rear of the car - my reflexes are just not quick enough (getting old, I guess!)
Nope, tires of the F-Trainers are just not satisfyingly modelled. This will be sorted with the next update.
