Earlier quoted context omitted.
Almost everyone means an electric kick scooter, not the vehicles in Vietnam - those are motor scooters.
Which I also find a weird language abuse. The original meaning of "scooter" is the vehicle in Vietnam. Why did we suddenly agree to call those "kick scooters" as "scooters". This is even more confusing for companies like "scoot" that rent both "scooters" and "kick scooters"
Then in 1917 it was used to refer to the children's toy.
