Is there a source for this? I live in Denver and am currently staring at a dozen Lyft scooters and a few bikes parked on the corner next to my apartment. Lime also operates scooters and bikes, which I usually see parked across the street at the apartments next door.
There are a few places that are geofenced (e.g. along 16th St Mall), but judging by how many people I see riding them on e.g. Cherry Creek trail as I'm biking, I don't think they're generally banned.
