Speedway is a simple sport, with very complicated rules. Get the rules back to basic, based on 4 riders getting out of the gate as fast as possible, keep turning left for 4 laps, and try not to knock each other off. As opposed to a referee deciding that a rider, got too good a start, and call them back, stating that somewhere in the rule book he can find justification for doing so. Only an example, otherwise I would be here all day. It might help if speedway rules were the same globally, never mind that we had 3 sets of rules in the UK alone
