there are all over our streets, look outside your window. Your city has been designed so that huge cars can ride around. Don't you wonder why you have to walk so much to get from point A to point B? And risk your life every time you cross the street at specific crossing points?
When cars start driving on sidewalks or being parked on the same, you might have a case. Until then, scooters are nothing but a toy for obnoxioous hipsters with no concern for anyone or anything other then them being too lazy to move their nicely oiled beards two blocks using their feet, like all normal and decent people do.
