Car jacking

Car-jacking is the forced theft of private motor vehicles from their drivers, similar to high-jacking of an airplane. The thief may pose as a hitchhiker or a lost pedestrian asking for directions. Threat of violence or genuine violence may be used to remove the driver from their car. Using a technique called [tamponnage], thieves stage an accident by bumping from behind with another car, forcing the driver of the car to get out.
