So, being a safety conscious rider with 10 years riding and five bikes under me, I'm more than a little chagrinned to tell you that I *nearly* turned left in front of a motorcycle in my cage the other evening.
Broadway westbound turning left onto Fraser, evening, intersection cleared and just as I started to go, an oncoming vehicle appeared over the rise. My brain thought bicycle, relatively slow moving, there's time/space, and I started to make my turn.
Well! Turned out to be a small ~80's Japanese motorcycle with a single small round headlight, black (and chrome?)....meaning no colour to it, holding what appeared to be a far right line, as a bicycle would. Of course it was moving significantly faster than a bicycle and fortunately I realized all of this in time to come to an abrupt stop and not cause a collision.
What's my point? Yes, it's very upsetting when a cage doesn't respect your right of way, but shit happens, and we owe it to ourselves to be as visible as possible, and to project what we are and what we're doing.
