I assume they would be required to use bike lanes in most American cities. I am concerned about the liability involved. A local journalist here in Austin was hit by a drunk guy on a scooter badly enough to dent her driver-side door and render the door inoperative. Then he claimed she hit him. His auto insurance, if he has any doesn't cover his usage of electric scooters.
So she was facing a liability for fixing the car, perhaps some sort of insurance fraud on his part, AND her insurance was going to list an incidence of her "striking a pedestrian." Fortunately she found out there was some CCTV footage that exonerated her, but all of that just so some drunk a--hole can zoom around on a scooter and the scooter companies make money?
