The most famous tunnel is the thirty mile “Chunnel” between England and France. Thirty miles of air is a lot to push around, so engineers have come up with a clever solution. The Chunnel is actually two separate tunnels, connected by cross passages.
The same thing happens to the air in the car. When the car stops the air keeps moving forward. This results in more air, or higher air pressure, in the front of the passenger compartment.
