I can’t speak for everywhere, but back in college, people would zoom across on their scooters with no regard for safety. Down the hills, through pedestrian crowds, on the road, etc. They also never wear safety gear too.

I know a friend who fell really badly because they needed to brake hard since the car in an intersection pulled up too far. Luckily she just needed a lot of bandages and ointment for about a month.

I’m not saying e scooters are a bad thing, but roads in the US are not built for them (esp since bike lanes are not well maintained) and people do not wear gear for the fall
