A 4-year-old can't do very much damage -- unless that "car" is a full-size truck.
In a new ad for Volvo, the motor company gave a little girl free reign to drive an (empty) Volvo FMX truck around a gravel-covered obstacle course using a remote control. Stationed on a high platform overlooking the course, she plows the truck through stacks of tires, muddy puddles and even a small building.
