Vespa-like electric scooter company operating in NYC for the last few years.
Solves a ton of problems:
1) faster snd operates in traffic (so less issue with their 25mph speed vs bikes, not operated on sidewalks so fewer peds to mow over, etc)
2) requires full-face helmet use and cursory safety training
3) street parks, and user is liable for tickets, which keeps them off the sidewalk and brings the city revenue
4) they’ve been good citizens, responsive to issues their riders cause
5) I don’t want to die from embarrassment being seen on one.
