Part of the issue is that there is no designated area so they are left either perpendicular to the curb on the road side of the footpath or next to the wall on the shopfront side.
I would assume Lime got a permit so Police can't simply hand out fines for obstructing the footpath.
The speed issue is also an issue but mainly of educating riders - I was almost run over last week when I started to move sideways hearing a scooter passing from behind on one side and narrowly avoided being hit by a second scooter passing on the other side - both traveling at full speed.
You don't see cyclists riding fast on the footpath where there are pedestrians - scooter riders don't seem to follow that etiquette. I much prefer the laws in Victoria where only children are allowed to ride on the footpath.
Is it because it is a paid service that they appear to feel entitled to go fast or weave in and out of pesdestrians where a cyclist would often dismount or go on the road?
