Yes, there is a phenomenon known as the "Bernoulli effect" that creates a low-pressure area, commonly referred to as a vacuum, behind a moving car. When a car is in motion, the air flows around it, creating different pressure regions. The air above the car flows faster than the air below due to reduced aerodynamic resistance. According to Bernoulli's principle, an increase in the speed of a fluid (in this case, air) results in a decrease in pressure.
As a result, the air pressure behind the car becomes lower compared to the air pressure in front of it. This low-pressure area, commonly referred to as the "wake," can be experienced as a vacuum-like force if you are following closely behind the car. This vacuum effect is why you might feel your vehicle being pulled slightly forward when driving closely behind a larger and faster-moving vehicle, like a truck or a bus.
The presence of this low-pressure area has implications for aerodynamics and fuel efficiency, which is why car designers strive to create shapes that minimize drag and optimize airflow around the vehicle.
