Bicycling in Hong Kong? Not so much. (Qualification: I walked Honk Kong central/west and the area of Kowloon from Mong Kok south. So it’s possible I missed something.)
Most of the few people I saw riding bicycles appeared to be delivering something.
Parking? Forget it. So people lock to anything they can find.
Lane control. Depends. The video below is typical of what I saw.
