We don't have rental scooters in my small city, but I've still almost killed a few scootybois when pulling into an intersection near my house that has poor visibility of the sidewalk due to big buildings on either side. It's easy to spot a pedestrian or even a runner coming, but I only have visibility of maybe 20 feet of sidewalk in each direction which makes it literally impossible to be prepared for someone tearing down the sidewalk at 20+ miles per hour. If you are going that fast, it's incredibly dangerous to be riding on the sidewalk and I'm shocked I haven't heard of anyone getting killed in my area yet. I've never seen someone wearing a helmet while riding one and some of these are definitely moving close to 30 mph.

In a just world, a folding electric scooter is a great solution to shitty suburban zoning and makes it a lot easier for people to get from their houses to the store or somewhere 1-3 miles away. Unfortunately it seems like the worst kind of people are buying them due to how accessible they are and the complete lack of regulation.
