Over here in London England, cars are not actually towed away. A special flatbed truck shows up with special equipment on the back to lift the car up from the ground and carefully place it on the truck, where it is secured before before being taken away. Mostly used for serious parking violations where the position of the parked vehicle is considered a hazard to other drivers. It must be a shock to a car owner to see his car pass by on the back of a truck.
