Are they referring to the fines from littering their scooters all over town?
No idea how it would be achievable it is entirely possible that the user parked the thing correctly but a kid passing by moved it later.
Many years ago in Paris (France) there were normal (actually terribly heavy) bikes for rent that had dedicated stands, you unlocked them with a card or similar, and you had to return them and lock them to another stand, otherwise you kept paying the rent (it was far from perfect, but at least created not this kind of problem).
But I was talking more about the US$ 500 one for driving on the sidewalk:
>And scooting on a San Francisco sidewalk instead of in a bike lane or road can earn a fine of $500, even if there’s no bike lane available. That fine is split between the scooter company and the scooter rider.
That one should be all on the rider, shouldn't it?
