I use my scooter a lot in San Francisco and I’ve found that I’m normally going faster than many of the bikers in the bike lane (>15mph). I also don’t have that problem turning, although sometimes I cheat and kick-scoot at sidewalk crossings. It would definitely depend on the environment though - I’m sure in more heavily suburban areas with faster speed limits, more lanes, and less stop-and-go they would not feel safe to ride around cars. But I do think they’re pretty compatible with biking infrastructure
