Can you tell me about the car culture of people modifying regular cars in the US to make them sports cars?
<|assistant|>
In the United States, car modification is a popular pastime for car enthusiasts. People often modify regular cars by increasing their engine power, suspension and brake system performance, as well as the appearance of the car. This modification is done to create what is called a ‘sport compact’ or ‘tuner’ car, which is an improvement of the original car in terms of performance and visuals. These custom-tuned vehicles are commonly seen on the streets of the US, as people take pride in sharing their unique modified cars.
