The advantages in using them in large commercial vehicles aren't necessarily present in small passenger cars.
Compressed air.
No, they use air pressure or actually the lack of air pressure to stop the vehicle. The brakes are fully on until pressure builds up in the tank releasing the brakes. When you push the brake pedal this removes air from the system and applies the brakes.
No for they can use compressed air to 'levitate'
just air with all the plugs out
One obvious place is in car tires. Refrigerators, freezers, and air conditioners use compressed gases. There are many other uses.
the brakes use friction to stop the car
One of the most common is the bus or heavy goods vehicle - fitted with air brakes. Similarly the brakes on trains. However there is a huge range of industrial tools, machines and control systems powered by compressed-air.

Air compressed cars are cars powered by compressed air. A compresser is used to generate high pressure air, and that air is then in turn used to propell the car. An electric engine and or a gas engine is still needed to run the compresser but unlike hybrids and other combination vehicles the air compressed cars use either of these engins to power the compressor only.
Compressed air cans freeze when in use because the rapid release of compressed air causes a drop in temperature, leading to the formation of ice on the canister.
Compressed-air stunners for smaller animals came into use after World War II
Yes. It is very powerful with compressed air though.
