For everybody's sake I hope the rotten things are banned at every motorcycle meeting. We made sure the overseas visitors knew they were banned in Australia when we held the World Solo Speedway Round as our experiences in the UK where we encountered them at every track almost drove us insane. Lucky for us they are not used here and it's crazy where racing machines have to be so quiet because of the noise polution situation (and I expect it is the same over there) yet these monstrous things are allowed to annoy any spectator who wishes to hear comments and results over the PA.
