Common sense would dictate that when riding, keep your hands, legs and feet to yourself. Obviously, CS isn't always common. Based upon a few "unfortunate accidents" I have seen, I think it would be a good tip not to ride stoned, nor try to steal a bike when stoned. I need to find that video. One last tip, it is usually a good idea to keep your feet on the pedals. Having seen a few people miss the pedals and get their foot caught in a moving bike or unmoving pavement--- Well, lets just say, I love the sound of an ankle snapping in the morning, so long as it isn't mine.
Cheer, Steve
