Technically, it works. You know the doppler effect, the way a car's engine noise changes as it passes you? That's because the sound waves "pile up" and are closer together as their source approaches you, and "spread out" as their source moves away.
The same thing happens to light. (http://en.wikipedia.org/wiki/Blue_Shift) The faster something is coming towards you, the more the light "stacks up" and appears to be of a higher frequency.
In order to get blue-shifting, you really need to be going at a significant fraction of the speed of light.

Now to get a car that goes at semi-light speeds...
