In most places, this is the most serious form of vehicle theft, since assault also occurs and the method of taking over the vehicle is essentially a robbery, a more serious form of theft. In some carjackings, the operators and passengers are forced from the vehicle while the thief drives it away him/herself, while in other incidents, the operator and/or passenger(s) are forced to remain in the vehicle as hostages. Some less common carjackings result in the operator being forced to drive the assailant in accordance with the assailant's demands.[2] Fraudulent theft: Illegal acquisition of a vehicle from a seller through fraudulent transfer of funds that the seller will ultimately not receive (such as by identity theft or the use of a counterfeit cashier's check), or through the use of a loan obtained under false pretenses.
