you can be assured: if a cyclist ignores a red traffic light, they have checked before if that's a danger for them. If I ignore a red light it's often times because that is even safer for me. many cyclists get injured because motorists pay no attention while making a turn right maneuver.
so if I deliberately run over the red light to avoid that, I don't need motorists honking at me. I know very well what I'm doing and why. they don't.
and as for the "mutual understanding on both sides" thing: people blabber a lot about that. it's an empty phrase. what is there to understand? tell me. please.
