I think it depends on the culture of the area. For places where people are basically law-abiding, that might happen. Where I live in Oakland, CA, there's not a chance. I get run over by cyclists on the sidewalk almost daily and the scooters is just making it worse.

Which isn't to say I want to regulate them more. It's just sort of pointless in a city where the populace doesn't follow the existing rules, and there's no political will for law enforcement to do anything about it.
