<human>: I commute on a pretty heavily traveled interstate highway every morning and every evening for about 50 miles one way. I've gotten fairly good at ignoring stupid drivers, but today took the cake--and it was fate that exacted the revenge for me.

Now, I have a little car and can merge into some tight areas. I have my turn signal on and am clearly cruising for a merge point. Usually a car and I will trade places--I get into their lane and they take my "spot" and all's well. 

Not today. Today, I hear a warning "grRRRRRRR" of a revving engine. Peeking over my shoulder, I see that a rather nice looking black car seems to be growling at me. I check to make sure that I have enough space, and say "screw it" because no one revs their engine at me to intimidate my little wimpy Yaris and gets away with it.

I merge into the lane between his car and the next with plenty of space to spare.

Now he continues revving and being an ass, to the point where I can hear his engine above the wind and road noise and my rather nice audiobook. Accordingly, I slow down to 65 mph in the 55 mph zone--hey, it's the fast lane! They've  been cracking down on speeders lately!

After a few seconds of this--and me clearly not speeding up to then hit other cars in front of me--he decides to pass me. I think good riddance and continue on my merry way.

Strangely enough, I continue to hear the car growling somewhere in front of me. Turns out, no one else is scared of his revving, either, and he's only ended up one car in front of me when we both take the same exit.

Oh, road congestion karmic revenge, how I love you. And thanks to your inconsideration, I got to listen to your frustration for a very, very long time--and giggle maniacally to my empty car.

Can you condense the text into a few key points?
<bot>: Guy with a fancy car thinks he can scare me into not going in front of him or driving at the speed limit. I can hear his frustration all the way to the office, and it was glorious.
