I've actually been contemplating selling my One E+ over safety factors. I don't really see them as particularly dangerous with the right gear and sane riding, but I am 51 and a widowed father with kids to take care of. Same reason I don't have a motorcycle either.
I scarcely rode mine this last year at all. It has been super convenient for doing things like dropping off or picking up a car at the mechanic, but Uber works too.
