Yep, these days the brake tap method will simply earn you an enraged response, as per the OP's story.
Last Friday night on the way home from work, had a gent in a late model Chevy Monte Carlo come screaming up behind me - with his high beams on - just as I'm coming up to the stop sign to turn right onto the main two-lane secondary road heading toward home. He finally turned off the high beams when he was about 5 feet off my rear bumper.
Apparently he was uber pissed off that I actually came to a full stop before turning right. I turned right and started accelerating. He ran the stop sign, turned right as well, and immediately jumped into the left hand lane - on a two lane road with double yellow line - and floored it to go around me while I was still accelerating.
I just kept accelerating at my normal rate, and he roared past me as I was coming up thru 50 mph. As he moved back over to the right lane, still accelerating, by now several car lengths ahead, I demonstrated to him that my Jeep Liberty had high beams as well - equipped with Sylvania Ultra Stars.
I stopped at 60 mph, my usual cruising speed - this guy must have been doing near 80, as within less than a minute he had disappeared around the next curve over a half-mile down the road.
