Same thing happened to me yesterday. I am adjusting from three years on night shift, so the daytime commute presents a brand of motorist idiocy I am not familiar with. Heading down Garden of the Gods Road yesterday; a road where I consistently hit 35 mph in traffic, I am faster than traffic at the interstate by about 5 mph. This good ol' boy in a huge white pickup/beast, speeds up only after I signal to get to the left of the right turn interstate merge, rolls down his window and mumbled something very loudly. I know, an oxymoron, and he was the latter half of that. He had to stop about ten feet in front of me, so while he was rolling up his window I flashed him the Terminator stare and asked if he was in such a hurry because he was running late for his OB/GYN appointment. Typically I don't respond to idiots, but I was feeling it yesterday. Plenty of folks around and there was no way he was exiting his vehicle at the merge of an onramp.
