Laser Headlights Promise More Intense, Controllable Beams
cartechboy writes "Soon, your new car's headlights will be powered by lasers. The 2015 BMW i8 is entering production, and it's the first vehicle to offer laser headlights. These new beams offer a handful of advantages over LED lighting, including greater lighting intensity and extending the beams' reach as far as 600 meters down the road (nearly double the range of LEDs). The beam pattern also can be controlled very precisely. Plus, laser lights consumer about 30 percent less energy than the already-efficient LED lights. Audi is among the short list of other auto manufacturers to promise laser lights in the near future. But the coolest part of all this? When you turn on a set of these new headlights, you'll be able to scream, 'fire the lasers!'"
Do not look into headlight with remaining eye.
just remember to turn them off before cresting a hill, because otherwise you will be fined and/or imprisoned for firing lasers into the sky in an effort to down aircraft.

I'm pretty sure it's stuck at 186,000 miles/second.
Release the coherent photons?
