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 
Ding ding fucking ding.
I keep thinking about something I read on this site a few months ago, paraphrasing here:
If a child is killed by a car, that is the responsibility of the driver and the infrastructure. Not the child or their behavior. That is something that shouldn’t be able to happen.
Separated bike paths that are more extensive than the road network. Being on the same path as cars has to be the most difficult, annoying, slowest, way to get to your destination. Pedestrian barriers along most car roads. Tight roads with low speed limits so if a collision does happen no one dies. Make rental scooters and bikes free to use so that children don’t feel the need to save money by piling onto one scooter.
The solution to this isn’t taking away one of the only methods that children have to get places on their own.
We're not talking about the US here, there's an excellent system of public transport in place. Kids can just take the bus.
The infrastructure in Vantaa (Helsinki region) is very good compared to most of the world. There are plentiful separated bike paths. Most likely these girls were doing something dumb considering it was three girls on the scooter. The police are considering charging the driver with “aggravated endangerment of road safety” which implies that they were likely doing something to make the driver upset (not that it excuses murder).
I guess I’d have to see the exact road where it happened, but infrastructure doesn’t work if people go out of their way to use it incorrectly e.g. riding scooters on the road where only motor vehicles and bicycles should be.
Bicycles still exist. Electric scooters are uniquely dangerous and stupid. They cause a lot of problems in urban centers while not adding any significant benefit over the bicycle.
