I don't know about the rest of the world but these electric scooters you pay for by the hour are all over American cities. I suppose they can be fun but they can also be a nuisance - and dangerous. Someone has apparently organized a taxi rank of them at 7th and Market downtown but it is common to see them flat on their sides, blocking a sidewalk. Helmets are recommended but nobody uses them. (Who carries one around?) I've read that there are a lot of visits to emergency departments by customers.
There are a few different brands on the streets of STL. The mix changes but the most common these days is Bird. The name faces the front on those little electronic boxes so you can't see it here. No one my age has any business riding one anyway.
