I was on my motorcycle at an offramp, second in line in the left lane, waiting for the light to change. Another motorcyclist split lanes up to the front and stopped to my right, a bit ahead of me. The light changed, traffic moved forward, and Mister Dumbshit on a Motorcycle made a left turn. From right in front of me to left in front of me. Luckily for him, me, and all the traffic behind us (who would have been inconvenienced by this ass-hat's squiddery), there was enough clearance for him to pull off that idiotic stunt without turning a dangerous situation into a crash. (I-280 offramp to Monterey Boulevard, ~7:10 PM today, just in case shit-for-brains on a dark blue or black motorcycle is reading this. I hope your ears are burning. Do you know what you would have done had I accelerated a bit faster? You would have low-sided both of us. Do you know how close the car behind me was? I wonder if you have insurance.)
