lol my son did something liike that once with my mustang. i had gotten in the habit of letting him start it in the morning to warm it up before school. so one time i gave him the keys to start it up by himself. i had left it in gear the night before, so when he let the clutch out after starting it, the car went across the street and into the neighbor's front yard. luckily nothing else happened but it freaked us out.
he was about 14 or so when that happened. it was the last time he started it himself
