I’m increasingly of the mind that while ebike rentals and shares are perfectly fine, e-scooter rentals should probably be banned or heavily regulated.
I see a huge number of people who lack the balance necessary to walk off of a moving escalator naturally. I definitely don’t trust them to use a scooter.
Bikes are much more self-correcting at speed that scooters, and scooters seem to give a lot of people all the rope they need to hang themselves.
I often ride a bike (especially a citibike) without a helmet. But I would never get on a scooter without one.
