I say "guy on a bike", because I would hesitate to call him a "commuter" or a "cyclist". It was just a guy riding his bike. No helmet or anything that would lead me to believe he was a regular cyclist.
Plus, he was disobeying a few traffic rules. Against traffic, and riding through a red light. He rode ride in front of the motorists turning left and got clipped. He went down, and busted his head open. He'll be alright, though. But the poor guy who clipped him will need some bodywork on his '60s Corvette
Seeing people flagrantly disobey traffic laws really irks me. It's knuckleheads like this yahoo that make motorists think that all of us are irresponsible.
