Say that instead of starting at 95 km/h you start at 120 m/h. For a certain time you will be going faster than 95, so the air drag on the surface of car will be greater. This friction will cause the surface to become hotter, creating a "warmth bubble" of hot, rarified air around the car. In the right conditions, this "bubble" will have zero resistance on the car, letting you coast indefinitely.
Just kidding ;P
