I stopped at a four way and then took my turn, the car that followed me got on my a$$ I then gave it more throttle and when it shifted a giant cloud of black smoke appeared, it's never done that before, wait for it........the car that ran up on me was a prius, he swerved to the right to miss the cloud and then stayed back....way back. Priceless. All diesels gave my old merc a virtual high five. And then I bought her a tank of fuel.
