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

After 6 months of practice only few bikes were faster than my scooter (25 km/h), I never experienced issues with turns.

Only issue is the rough roads - when I want to ride on the rough roads I use bike.

In every other aspect e-scooter is better: doesn't require special outfit; I don't sweat; it's compact enough to take it to the shop or cafe (without bending); less details I need to care about - pedals, brakes, speed switches, saddle - I just use what I've bought and it works fine. My bikes usually worth ~$500 (same as e-scooter) and they requiere some fixes/replacements from time to time. Scooter had just one flat tire replacement, that's all.

At least where I live scooters have a max speed of 25 km/h, and very few cyclists go faster than that in a city environment.

No they don't. Electric scooters are definitely fast enough for bike lanes. Most cyclists in urban areas are only going like 12-15 mph, well within electric scooter speeds.
