Well, actually, Relativity says the car can't travel at the speed of light, so if you're talking about a car actually going that speed, you're talking about a non-relativistic universe, which means anything could happen.

If you are in a car travelling slightly slower than c (which is allowed in relativity), and you turn on the headlights, then the driver of the car would see the headlight beams as travelling away from the car at the speed of light. The stationary observer would see the beams travelling at the speed of light relative to himself, and so would say that they were not moving that fast relative to the car.

Simple, ain't it? [img]/phpBB/images/smiles/icon_biggrin.gif[/img]
