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 
They're so much worse than bikes. The design encourages you to be reckless and they're not nearly as easy to control as a bike. The wheels are too small to handle uneven ground well so you could hit a bump you didn't see at 25-30kmh and eat pavement. And I've seen several people walking their personal e-scooters that have run out of battery. They're too heavy to kick push like a normal scooter whereas an ebike is still a bike if it runs out of battery.
