Is it time to start calling out bad cyclists?

The lesson I'm taking away from this is to remember to acknowledge people. I often gesture my intentions to other cyclists, but a quick wave would have told him I had seen him and I wasn't just pulling out without looking.

Oh, so in future if someone smiles and waves, and then pulls out from a minor road in front of me on a major road that is all fine?

Acknowledging you are about to pull a dick move, does not make it any less of a dick move.
