No, that's more or less it ,except you have to be disabled to ride a disabled scooter, so legally, if grandma has a turn outside Boots and gets taken to hospital in an ambulance, only a disabled person is allowed to ride her scooter home for her. But there is no legal definition of disabled, so it's up to the discretion of the copper whether it's legal or not.
It would be trivial to allow the same for swegways or smegways or whatever they're calling them (the Chinese, less worried about copyright, just call them segways).
