Sorry for posting all these news articles, but this is just insane:

Although unable to reach the accelerator, a four-year-old boy managed to put his mother's car in gear and make his way to the video store, a quarter-mile from his home, about 1:30 a.m. Friday. Finding the store closed, the boy drove home.

Weaving and with its headlights off, the car got the attention of Officer Jay Osga, who first thought he was following a car that had been left running at a gas pump. He flipped on his lights when the car turned into the apartment complex and struck two parked cars. The boy put the car in reverse and struck Osga's cruiser.

"He's 4 years old. His mom didn't even know he was up," Osga said. "I don't think he even realizes what he did." No charges will be filed against the boy or his mother.
