The act of stealing a car from a driver through force or fear is generally classified as a form of robbery, specifically carjacking. Carjacking involves the use of intimidation, threats, or physical force to take a vehicle directly from an individual. This crime not only includes the theft of the car itself but also involves the potential harm to the driver or any passengers.
In legal terms, carjacking is treated seriously due to the violent nature of the crime and the immediate threat it poses to the victim's safety. Penalties can vary significantly depending on the jurisdiction but often include substantial prison sentences and fines.
