Enthusia has a similar system. Every contact you made accounts to your stats and the price will be reduced on that race.If they don't sort out the netcode GTSport will be a huge exercise in frustration for a lot of people. I'd like to see a driver rating system more than anything but I just don't see it happening for a number of reasons. Primarily I think PD will see it as a hinderance to people going online and that's the last thing they want. Their primary interest is to move units, not fair and clean racing. Assetto Corsa is highly moddable and one of the guys came up with a driver rating system on his own called Minorating, which is a simple type of system I've advocated for a long time, that is, it simply counts laps/contact, with only a slight weighting system if fault is obvious but even then both drivers get contact points. It changes behaviour online and it works. I've had some of my best open lobby races ever, in any game, on MR servers lately. It's available to all hosts and you can restrict entry to your lobby to any rating level or leave it wide open.
Though on that game is a bit overkill. Should have been better in some way.
