Drivers should all have rankings on the following:
1. Something around your average finish, weighted by the size and strength of the field and the length the race.
2. An accident/collision/safety rating.
3. A quit ratio indicating how often you stay to the completion of races.
Each of the above should visible to all participants in a race and online hosts should able to set minimum standards for their particular rooms which will prevent those not up to standard from entering to begin with. All rooms should able to be set up and change on the fly, whether the races are for fun meaning they don't affect your stats, or for real. People still need a place to gather to do things other than racing, like drag racing, cruising, dirty races etc.
