Einstein's Relativity, the key word here is relativity, which comes from the word, relative. Motion is relative.
Another fact is that nothing can go faster than the speed of light.
Therefore, what we get is, the driver will see the light travels away from him at the speed of light. Remember, the car and its headlight is not moving in relative to the driver.
But to an outside observer, the car is moving in relative to them, therefore, they cannot see the light leaving the car, because the ultimate speed in the universe is always the speed of light.
