The schadenfreude tastes so good.
Hah...
My $0.02/analysis:
1) If you're going to take a call, hands free or hands on, pull over and take it. The person on the other end will be happier if you're paying attention to them, and you won't be inconveniencing anyone else.
2) So what if the car pulled a little close; looks like the car had given him 3-4 feet of room.
3) Should have expected dumb moves from a driver who pulled up close, honked, and drove around, but he didn't (If anything, having his high-beams on and accelerating/chasing probably only made the driver more annoyed).
4) Should have noticed the light was red, and there was no point in accelerating to it, with nobody behind him and a mild down-hill grade (Saves on gas, tires and brakes..)
5) Should stop punching peoples mirrors off; if he could prove that the person in front of him had caused the accident, his insurance might have gone after the drivers insurance for bike repairs. Instead feels the need to break a mirror off which would just result in a counter-claim and negate any possible benefit.
6) Looking to pick a fight with a car is probably second worst idea to make while on a bike, only to picking fights with lifted trucks/semi's...
TL;DR: Guy is gonna bite the dust real good one of these days. For him, it's definitely a matter of when.
