I am with zen. Years ago I surprised myself by jumping out of my tiny little 2-door Japanese econo car, which had just been rear-ended by a Mack truck, and swearing a blue streak against the big, burly Mack driver, who went mute.

I also would have filed the report if nothing else but to give this moron pause. So freakin what if he had his blinky on? Legally, he has no right to go wherever he wants just because he puts his blinker on - he is responsible to look first and you were riding properly and did nothing wrong. Glad you're ok.
