Good for you for standing your ground! I wouldn't have moved, either.
I got honked at today after making a perfectly executed, legal left turn, with a hand signal. I guess stupid woman was mad that I had the nerve to take the lane and make her wait, which she didn't even have to do, since I'm sure I was going the speed limit (it was a slight downhill). I wish I could have caught up to her, which I almost did, and would have done if she weren't speeding. I was ready to read her the riot act.
