Currently, if you are in a race and get in a car as passenger you are automatically disqualified. Remove this and allow racers to get in their own cars as passengers, so in extreme cases they can stop, be passengers for a short time (I'm not talking about staying that way for half an hour) and protect themselves from the Rustlers' shots until they give up and leave the zone.
I know this won't solve completely the racing problem but at least it would be a little help.
