I agree. What pushed me back to GT4, other than the greasy/ice covered feel of the tracks, was the "full contact-combat" style of racing that normally happened when racing on-line. Due to the limited vehicles available and the choices these "controller using wanna be drivers" ended up racing, I started to call them "Children of the Clio". My apologizes to the Steven King fans out there, but at times it was an absolute nightmare.
Maybe the venues you are allowed to participate in will be tied directly to your driving style/ability? Sounds to much like i-racing, maybe. But I like the idea of how the stewards in certain professional series will penalize a driver for being "overly aggressive". i.e. F1 and V8 Supercars. Black flag pass through the pits, hold in the pits for a lap. Something more realistic than just taking their accelerator away for a short period of time. I also didn't like how you could follow your racing line, have some idiot bonsai into the corner just before you turned in and then YOU take the penalty for turning into them when they shouldn't have been there in the first place! Sorry a lot of bad memories came to the surface there.
