Snap oversteer is an understatement, some of these cars are just ridiculous. I like oversteer as much as the next guy, Yellowbird, BTR are among my favourite cars, but some of these cars are just ridiculous. The Cizeta Anniv version for example. I had someone watching me drive and she said the difference between a spin and a decent corner was about 1/8" of wheel movement.
Yes they can be driven, anything can be driven. But are they "right" physics wise? IMO no. If they were there roads would be littered with the hulks of crashed supercars just going to the corner store for groceries
Now that I think about it I have some "proof" that these cars aren't right. Take an RGT and run if for a few laps on stock tires. Then take the Cizeta 15th Anniv. These cars have near identical weight distribution, within 1 point either way and only 6 years apart so they should feel similar although the Cizeta might have slightly less grip if PD programmed the tires as being a few years older.
Now tell me something isn't wrong
