I used the lime scotters in Paris 4 years ago, in the pre pandemic times. Oddly useful the few times I used them. Though some Vandal was drawing over the qr codes, make some of them unusable.

I see them in Cambridge where Harvard students own them and zip across the river to the athletic center.

The can go quite fast and as a biker then can be annoying when the try to go past you at 20 mph, but honestly in the bike lane is probably the best place for them
