I prob'ly would have reacted the same way... but when I remember to, I make sure I"m on the "already through" part of the intersection and all the way off the road. If I'm going to turn, I can go the extra few feet. (However, I don't know that intersection's layout. 'Round here it's mostly cornfields )
My guess is there were other unrelated anger issues happening with the driver - it was bizarre behavior.

ONce three of us were resting at a corner - and pretty much off the road - and a car whipped around the corner too fast and while we were trying ot get away - okay, I confess, I was still at the "what?!" and looking at the license plate - but fortunately my friends were already in motion - the driver clipped the back wheel of one bike, then swerved and took out a mailbox on the other side of the street... pulled to a stop a hundred yards away and started backing up (at which point *I* started heading into the cornfields, with some kind of Rockford Files scenario going on in my head).
So... I really try to get all the way off the road.
IT was a lady who had been "having an argumetn" with her daughter who wanted to help drive (?!?!?). She paid damages and she got a ticket.
