MAYBE and that is a BIG maybe, the euro streets are somehow safer than the US streets....I rode for 30 years....tried on a few rocket bikes, still prefer the cruisers...point is after all those many many miles I learned the hard way ( a few times) ALL it takes to send you off is ONE pebble, one old lady not paying attention or cant see the bike or a stray cat Dog or squirrel darting out at the absolute WRONG time..... somone said it earlier tracks can be deadly and they are specially cleaned and typically free of animals...doing that **** on any metro Detroit area street classifies you as an organ donor. NOW that aint all bad if the only person that gets hurt is YOU and someone needs a kidney......but typically in even moderate to light traffic bike accidents are a serious goat rodeo....bikes tend to bounce off stuff like a pinball and THAT is what makes activity like that REALLY stupid..... you are endangering someone ELSE'S life and that is where that kind of stunt gets seriously stupid and negligent and harmful! SOrry for the rant here but there is NO WAY that activity can be justified....putting other people in jeopardy for 'kicks' means you ain't right in the head and dont really give a damn about anyone else but yourself.......BAD PLAN
