Panda cars are often used to describe police cars that are primarily black and white in color. However, there are a few other synonyms used to describe these types of vehicles. One term often used is "prowler cars," which refers to police vehicles that are meant to blend in with their surroundings and are less visible to criminals. "Ghost cars" is another term sometimes used to describe these types of police cars. Finally, some people call them "stealth cars," which also refers to the way they are designed to be stealthy on the road and help officers remain inconspicuous while patrolling the streets.
