I have a good one, from NJ...
An older MPV was swerving eratically, dipping on Friday during rush hour. Mind you, this is on an on-ramp to the Turnpike. He cleared the ramp and took off. Not 30 seconds later, I come around a turn, with lots of blue smoke. The idiot lost it! He lost it on a curve and ended up hitting the curb, breaking an axle. He got out of the car and scratched his head... Needless to say, I laughed and yelled out instant Karma. I did pull over to help, but someone was already helping out the jackarse.
It made my morning commute that much better!
