I had it happen to me again yesterday, driving home from work.
Coming north on U.S. 75 just south of I-44, coasting downhill, speed slowly dropping from 70 to 65 (in a 65 zone), 100 yards before the downhill exit ramp to merge onto the I-44 eastbound access lane, a pickup blew past me in the left lane (he had not been following me in my lane--the closest guy was about 10 car lengths back), cut in front of me just in time to slam on his brakes so that he wouldn't tip over, and he took the exit ramp at about 30 mph. In my Boss 302, I can easily coast through that ramp at 60+, lose speed gradually as the ramp goes from downhill to slightly uphill to merge with the I-44 access lane. I have to yield to the traffic on that lane, so normally I accelerate as necessary to either merge well ahead of that traffic or to slide in right behind it.
But, no. Mr. Pickup Driver had his brakes on the entire time, so I had to do the same.
I smoothly passed him on his left as we merged onto I-44, but a mile or so down the road, here he came again, in the far left lane doing about 80.
Slack-jawed jackanape. In his mind, he's the only guy on the road who matters.
