I dont recall all the details but a young teenager (12-16 ish) in my hometown was bought a minimoto for his birthday. Him and his mates were riding it on the road doing laps of his block but unfortunately he hit a car head on going round a corner.
Not a nice way to go but I wouldn't want to be the driver in that situation.
Thing is, it's a brilliant sport when you get into it and do it properly, it's just not supposed to be done on the street or in a park.
As for banning bikes, can't see it happening. The reason above is exactly why I don't buy MCN anymore, if I want made up news I can do that myself
