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
Now that they have introduced new laws to punish death/injury by dangerous cycling it's only a matter of time before registration and insurance will be required to cycle on the roads. The playing field will be levelled then and there will be a raft of drivers reporting cyclist for cycling with undue care and attention. Then we will hear a different story no doubt. I see just as many bad cyclists as i do drivers, especially in the tight roads where we live.
