I don't know about scooters, but I'm in a city with a lot of Lime bikes. I spent a few weeks commuting to work using them and each day was a roll of the dice to see if the bike I got was going to be functional.
I don't know what's wrong with some people but apparently "drive it like you stole it" also applies to "rented it". Based on how a lot of those bikes look—and this is while Lime is actively maintaining and culling the fleet and—it seems many users end their ride by leaping off the bikes in mid sprint and letting it crash into whatever, sometimes punctuated with an angry kick or maybe smearing a little dirt and food into the seat and basket.
It's completely careless use that raises the ecological and economic price of these ride shares. If people were less shitty, they'd be way better in every respect.
