I haven't tried 'em in a bit, so to be fair, maybe it's better now.
But last time I tried:
Scooter coverage was too sparse to be useful.
If you did try to chase down one of the sparsely scattered scooters, usually it would be missing. No way to make it play a sound to help locate it, no way to report it was missing.
Gave up and just kept skating everywhere. Whereas I found Lime and Bird to be a practical alternative mode of transport, before they got kicked out.
