@no-passing: I don't think this should be enforced blindly. There's certain situations where it's better that mid-race joiners pass stragglers then be forced to stay behind them. If they're not allowed to pass any cars, then they're just one more car that might interfere with the leaders.
When I join mid-race, I try to stay as close to the main pack and as far away from getting lapped by the race leaders as possible. This usually means I pass people who are having a hard time controlling their car.
