So what I'm hearing is someone needs to start painting a bike lane across the lanes, placing large bike lane stickers on every car, and the start smashing headlights and windows.
It's fair, they destroyed something someone else relies on. Any destruction of mobility for disabled or less motive people is a personal attack on them, and deserving of defense.
Fun anecdote: my ow. City removed a bike lane only to add it back two years later. Cars that parked along the road where the lane was would often be vandalized, sometimes with a bike lane indicator drawnon the car. I don't think anyone ever caught the people doing it, but enough people were pushing for returning the lane (and someone on city council wanting more bike lanes) but it finally came back, unprotected and needing to "share the road" for anyone who just feels like driving in the lane meant for busses to pick people up.
