You could say the same thing about cars. In fact it's far more common for cars to be parked on pavements blocking access than it is for e-scooters. You just don't notice because you're used to it.
Largely because the people on scooters ignore traffic laws. I'm in an area of Atlanta where they are still allowed, and the riders regularly run stop signs and red lights without checking if a car is coming.
A bus can never kill anyone, it's public transportation and is therefore infallible. Cars are heavy killing machines remember, but busses and trains are perfectly magical and never harm pedestrians at all.
