Cyclists who think they are some sort of law enforcement officer, and those that where helmet cameras.
I think passively seeing and reporting is very different to going out looking for people doing illegal things is very different. I approve of the former!If driver is on their phone for 10 seconds plus at a red light and don't see someone looking through their window with a camera, it's not great and i applaud the po-po for making it easier to report these dangerous drivers
