Spirit guide said, "Look behind" and I saw the smoke from the (useless) brakes of a semi that was going the speed limit and about ten feet from my rear end.
I let go of the brakes, and got shot up the exit to Santa Rosa at sixty MPH like a pool ball hit by an evil cue.
Truck left hexagonal imprints from the bumper bolts in my license plate, and a blue smear on the bumper from his bumper, but that was it.
It's metal. You've seen "Donnie Darko" I presume?
