Pulled out in front of me and stopped trying to cross multiple lanes. I signaled him to go straight, and he didn't take it well. Said "Who the f@ck do...", before I yelled and didn't hear the rest. He reversed back into the driveway, then tried to follow me, but he'd backed up the traffic behind me and ended up back a few cars, then lost me when I turned into a parking lot.
I made no obscene gestures, just signaled to him to go straight.
Driver rarely signals, beware
