I’d be interesting to know what this is actually classified as, legally.
Riding on the sidewalk with a 500lb+ “mobility scooter” that’s basically a narrow car seems like it could raise a lot of questions.
That said, I’d love to see these replace full-size cars for people who still want/need to drive around town for errands.
I can’t think of any lane, ped, bike, or car, that would be happy to share with this.
