I was waiting for a turret cannon for those rough traffic jams.  This sounds cool.  Though a forward mounted Gauss rifle and electronics shielding for EMP would be cool.

I want phazers, I don't want to have to drive through debris.

Good news: Now you can blind on coming traffic from 3 miles away!  As a special bonus the hardware for your healight no longer consists of a $2 plastic housing and a $3 bulb - instead it will cost roughly $12 gazillion dollars to fix your headlights in the event of a fender bender.

So besides being WAY more expensive, what's the advantage?

As if I didn't hate driving toward BMWs at night enough already.

/I do like driving BMWs at night, though.

They are using a laser (monochromatic) to excite a phosphor (whiter light). Essentially the same process as a white LED. The laser light is not what goes out the front of the car.

The only advantage they really seem to claim is lower power, but who cares about the watts used by a headlight? That's in the noise margin when compared to motor power. (unless they were using these for Hybrids or electric cars, which would make more sense.)

It's the story that keeps on giving.

Also, the claim is that this technology allows better control over beam shape and distribution. Smaller emitters, too, which designers love, but I still think very tiny and very high-surface-brightness headlights are a safety issue.

I just bet they are only blue.

CSB: Friend of mine races his Jetta. Actually drag races it. Had some mild body kit stuff, mostly so he can rip it off for weight savings, and blue headlights. After driving it between races for a month, he switched the lights back. He got tired of oncoming Semi's trying to run him off the road in the middle of the night while driving home.

They WILL do that.

Because those bright blue HID headlights are not annoying enough, BMW must ensure their customers remain on the cutting edge of d-baggery.

Creepy evil car now has lasers?

I was going to say... seeing a couple of pinpoints in front of you several hundred feet away doesn't sound like very good illumination.

They're BMW drivers.  There are actual studies proving that BMW drivers tend to be dicks.  Of COURSE they want the brightest, blindyest lights possible because, fark you, that's why.

They don't care about spending a gazillion dollars on repairs, either.

Blue tinted lights are actually the worst. The blue wavelengths refract more in water making them inferior in rain and fog.

Early HID systems had a blue tint and a bunch of dopes started copying the color to "look cool".
