Motorcycle. Put the turn signal on, let it blink once, lunged across the double yellow, totally sideswiped me. Sent the bike spiraling across I-405 at rush hour. I came off two lanes into it, bike kept spinning another couple lanes. Stood up, looked at the guy, who yelled at me "you were going too fast!" to which I said YOU CROSSED A DOUBLE YELLOW! Would have been a $700 ticket for him if the cops had seen it. They didn't. On the plus side, I wasn't run over by six lanes of northbound traffic. And, thank god for crash bobbins. I'll need to replace 'em but the bike is largely intact. I'll need ~200 worth of parts to get it running again, from f'ing Nuremburg, of course. On the minus side, yeah. knocked across 4 lanes of traffic. Amazing thing is I was only an hour late for work.
