I had a coworker that fell off his e-scooter twice in two weeks. Ended up with a broken arm. Turns out roads in the US are shit, which is why we recommended a bike to begin with.
He was saved from serious injury because he was wearing a helmet. It’s not even controversial to say that if you don’t wear a helmet while riding a bike, scooter, skateboard, or any other wheeled vehicle that doesn’t fully encase you, you run a real risk of hitting your head and actually dying.
No kidding. I'm a decent cyclist. I've bounced more than one helmet off the ground with my head in it. This is why I always wear one, and always insist my kids do too.
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
