I used to cycle regularly as an occasional and enjoyable means of getting around. In recent years a lot less. Increased traffic is a factor, but the biggest factor is the increasing incidence of street harassment.

For the most part teenagers in various forms doing things like emitting sharp yells on driveby in attempts to shock and get a reaction. Also just yelling dumb stuff randomly:

I don't particularly care that this is a kind of a celebrity doing it for similar and dumb entertainment reasons. This is very unpleasant stuff.
