Is it time to start calling out bad cyclists?

^^ Why not send him an open letter via his employer saying more or less this. If you try to stop him for a chat he sounds like the sort of guy who will guaranteed fuck you right off by being a giant bell, your blood pressure will rise and then you're just wasting your energy not getting your point across.

Good point well made. I can assure you I'm not a violent man(not swung a punch since age 14) and perhaps the official route is the best course. Will draft a message and sleep on it.
Also, arguing with some pellet in front of the boss and our employer(pimped out private hospital) would not be a good look. It's been a fucking mare trying to prune trees all week above patients, ambulances, an endless stream of taxis and cars(and at one point Corny) and everythings gone super smooth until he came along and fucked with my karma.
