It'd be dangerous to pedestrians and non-motorised cyclists though. Of course, fit cyclists can cruise at 30+. But to get to that level, you've to put in serious effort and by the time you got the power, you know your responsibilities too. But giving anybody 30km/h vehicle that is legal on shared paths ain't good idea. If you're afraid of cars overtaking you, get a small motorcycle.
