This truck tried to back thru one of my conv. stores yesterday. There is no one in the truck when it starts to back up. Watch the backup lights. You see her in the corner start running to try and stop it. Notice how the video camera shook when it hit the building.

This is the video from the inside. Move up to about 1:30. It's amazing there were no cars in the stalls and no one got hurt and it only hit glass.
