Which equipment is found on the roof of a MOTOR car?

The equipment found on the roof of a motor car commonly includes an antenna, which is used for receiving radio signals for communication and entertainment purposes. Antennas are essential for radio reception, wireless communications, and sometimes for GPS signals. Their location on the roof allows for optimal signal reception, minimizing obstructions that would interfere with the antenna's functionality.

The other options—sensors, HVAC systems, and surge arrestors—are less likely to be found on the roof of a motor car. Sensors are typically located in various locations throughout the vehicle, including under the car, in the engine compartment, or integrated into body panels. HVAC systems, which manage heating, ventilation, and air conditioning, are usually located inside the car, not on the roof. Surge arrestors, which protect electrical circuits from voltage spikes, are typically housed within the vehicle's electrical systems, often near the power source or in the electrical control compartments.
