there are speed limits in eu too, but I still think their users are more likely to hurt themselves than someone who's trained, either by doing it a lot on a regular bike to the point that they're able to hold relatively high speeds, or going through a special certification process like a motorcyclist. It seems highly likely for a novice to hop on this new toy but be unable to safely navigate given how different it is from a car (e.g. you can't just slam brakes in the middle of turning)
