Road Karma

Punishment by divine intervention for previously committed road crimes. For example , cutting people off on the freeway , turning from the wrong lane , doing a California roll instead of stop , etc .

I was on my way to the airport and just when I was about to exit , damn ! Road Karma !! A huge SUV cut me off and I missed my exit and missed the flight . Next time I cut someone off I will remember "Road Karma"

road snark 

The release of pent up frustration in the way of sarcasm directed to all of the morons on the road, so said pent up frustration doesn't build into the more commonly known Road Rage.

After saying that the idiot in the oversized pickup truck who cut him off, was obviously over compensating, Joe laughed at his road snark.
