Just this week in Vantaa, Finland three 12-year-old girls piled onto one of those electric scooters you subscribe to with an app and proceeded to get run over by a car at a crossing, killing one of them
The app is supposed to have an age restriction but it's easy to bypass and you're not supposed to have more than one person riding on one, which people routinely ignore
I hate seeing kids and teens speeding around dangerously on those fucking things and then just leaving them laying around on high-traffic bike routes because they don't give a shit since they treat the scooters as completely disposable
Fucking awful bazinga-brained Silicon Valley-ass idea and business model. Actually, there are also bikes you can use with an app but curiously you don't see kids doing reckless shit with those, almost as if electric scooters were uniquely terrible 
Do you live in an area where scooters create issues?
Scooters are a solution in search of a problem if you live in a place that already has other sustainable means of transport (separated bike lanes, reliable public transit). Vantaa is one of those places. The scooters do not solve a problem that exists here.
People ride these things on the sidewalks all the time, it’s fucking annoying. Maybe there is a way to improve them like reducing their speed limits and adding noises like EVs have.
