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 
One of my hobbies is when a scooter is blocking sidewalk access, like would block someone using a power chair or a mobility aid or a stroller or anything, i pick them up and bodily throw them on to something concrete that isn't in the way. Seriously considering just carrying an angle grinder in my purse and sawing the cursed things in half whenever they're blocking public right of way.
I hate them so much. A bunch of bazinga shitheads just drop-shipped them all over the country to colonize and monetize one of the last remaining public spaces.
I would love a city that banned them and only allowed a municipally run bike share system.
We we could figure out how to re-flash the awful things again we could seize the means of propulsion. Shame they seem to have mostly fixed the firmware security.
