Downvoters: how is a scooter going max 15kmph a danger to pedestrians? For sure it is a danger to its rider if put next to cars.

For the metrically challenged, that's a top speed of less than 9mph. It's not even the top running speed of the average person...

Note, are we talking about Vespa style scooters or kick-style scooters? For the second, yeah, if capped at low speeds, should be fine on sidewalks.
