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 
The other day I got surprised by a couple on an e-bike flying down the sidewalk as I was leaving a store. They proceeded 20 yards down the sidewalk to where a worker was setting up some outdoor seating and went right up to them before they stopped and then just waited right there, making that person's job that much worse after threatening to hit them. I kinda think they got lucky and were just able to stop in time. small motorized vehicles either gotta have pretty restrictive speed caps or be prohibited from a lot of pedestrian areas. E-bikes one-hundred percent need to be in the road. Also mandatory helmets, but that should almost go without saying - except I hardly ever see anyone on an e-bike that is wearing a helmet.
