A car crashed into the back of a tractor trailer in California this week, and got stuck underneath the back left tires . . . and the truck driver never stopped. He had no idea the car was underneath him, and ended up dragging it almost a mile. Witnesses said it was four miles, but California Highway Patrol said it was less than a mile. This video is from another driver who saw it, and made the truck stop. Apparently the car's driver was okay, so at least there were no injuries.
