If you are aware and cautious a no fault system of driver rating can work. I've been through a few in iRacing, Grid and Assetto Corsa and it's simply a matter of being much more aware of what is happening around you and taking fewer risks. Drive it much like you would a real car basically. Problem is, will the casual fans be aware and cautious and will they enjoy it if they are? And if they aren't aware and cautious will they be relegated to racing with the other potato drivers all the time? Will they even understand what is going on or will they just give up in frustration?
This rather hits the nail on the head:
