I recently saw someone drive off with the gas hose still in their tank.
Another favorite from when I used to live on niag falls blvd was the people who would u-turn at the lights and run over the concrete median with 3, sometimes all 4 wheels, and bottom the shit out of their car. The surprised look on their faces was priceless, even though you think they’d be expecting that since the retards probably do it every time.
