Just come out of a race which was spoiled for me (for the first time in my life I was P1 !!!) by a bunch of tits who were out of the race by miles. They might have pitted or whatever so they use the rest of the race to practice. That's OK but not if they ignore the blue flags or crash half way up the straight and then collect the leaders. How about if you're a long way behind, say a lap or just under, if you crash into another car or the scenery enough to cause yourself more than trivial damage you get bulldozed off the track. IAFAIK at the moment you have to have a massive shunt to get towed.
