I don’t know where you live, but in the SF Bay Area the SF Critical Mass and East Bay Bike Party are both pretty casual events… To the point they attract the odd skateboarder or roller skater.
Responsible bike riders should publicly condemn Critical Mass. They are the type of people that make drivers and pedestrians hate people on bikes, and go out of their way to escalate confrontations due to some bike rider victim complex.
I’m not sure why responsible riders wouldn’t want to see huge groups of riders asserting their equal right to public space?
Critical Mass helped spur NYC’s bike lane growth. If you’re against direct action that’s fine, but it’s hard for me to see what works better in initiating long term transformation than direct action protests like Critical Mass.
I cycle to work on fairly rare occasions. My kids ride on city streets every so often. There is nothing that I’ve seen Critical Mass (or events like it) do that I think is positive.
