Unfortunately, I've had a similar experience -- the full nutty asswipe road rage monty: erratic driving, pushing his vehicle too hard for no reason, pursuing me like he was goddamn Steve McQueen in 'Bullet'...even the gun waving part.
And a friend, two years ago, was hit pretty hard while crossing the street (with the green) by a reckless motorist in, say it with me, an SUV. Not only did this gym rat hit my boy, he got out of his small house sized machine to deliver -- astoundingly -- a further beat down to my heavily damaged friend for **getting in my frigging way.**
That was a bad day; had to jump in to defend and got popped hard by that overclocked maniac (spat out the blood from my mouth and kept swinging, pain can be a motivator, I've learned). Cops quickly showed up, night sticks came out. By some miracle they accurately discerned who was the problem and skillfully avoided my head while raining 'compliance enforcing' blows on Frankenstein's lycra'ed monster.
There was commonality between the two events: in both cases the drivers turned out to be mood altered. Booze, coke and self administered roids -- to combine the two into a blur.
I wonder how much completely off-the-hook behavior that's tagged as 'road rage' is really the result of drivers not being straight at the time of the wildness.
We underestimate, I suspect, the role the mood altered play in daily life.
