yes, yes, yes. Some of the little scooters (with two wheels at the front, one at the back) are very fast, and even small children can go very fast on them. Loads of kids have them here, 2, 3, 4 year olds, and they zoom on the pavement. When I am reversing my car from our parking onto the street, I am always extra careful to check for kids but I always fear that a kid on one of those scooters will either hit my car or I will hit him/her. They are very dangerous. My kids don't have scooters, but if they'd have one they would have to wear a helmet.
