Automakers have been teasing us with demonstrations of laser headlights, but you shouldn't hold your breath.

A senior executive at Audi says LED headlights look so promising that there is no pressure to replace them with a new technology such as lasers.

Because lasers can generate a pinpoint of light, automotive engineers could shrink the optics in a headlight to create a very compact package. That would be cool, from an engineering point of view.
