People near me always use the bike lane as an extra lane to drive, turn, pass or park. I doubt I would risk using it myself, and I often see people just riding on the sidewalk instead.
That was pretty obvious to me. When I studied in Sevilla, Spain, there were bike lanes everywhere, but they are segregated from traffic, at the sidewalk level. I felt quite safe, I can't say the same for London for example.
This would also make electric personal transportation like e-scooters and e-bikes a lot more usable. I would love to see Bird and Lime scooters have a place to ride aside from sidewalks with formalized traffic control devices.
