Though it works pretty seamlessly in the cockpit of the car, there's a lot of tech wizardry going on behind the scenes. First, the CCC baked in Internet protocols that work with almost every device in the known universe.

Second, there's a lot of technology already in modern cars that the CCC could take advantage of in MirrorLink. BlueTooth, for example, has been available for hands-free in-car calls since 2001. Cars have had USB ports, mostly for music players, for nearly as long. More recently, cars are being equipped with WiFi, and MirrorLink will soon use that rather than the cable to connect phones and cars. MirrorLink merely takes advantage of all this technology to weave its protocol into the car you've already got, or the next car you buy.

MirrorLink also brings some new technology to the driver's seat, like universal plug-n-play, which means that when you plug a device in, it just works without a lot of folderol and downloads and drivers and ritual sacrifices.

It also brings virtual network computing to the car, which you may already be familiar with if the trolls in the IT department have ever taken over your computer rather than trudging up two flights of stairs to deal with your "problem." It's the mirror in MirrorLink, the thing that brings your phone's screen up on the car's screen and tells your phone which buttons you pushed in the car. Lastly, in addition to BlueTooth, MirrorLink can stream music using real-time protocol.

All of this, we hope, adds up to safer driving. "The technology conforms smartphone controls to the same Auto Alliance guidelines for driver distraction that govern how other in-vehicle buttons, switches and knobs function," the CCC said in an e-mail interview. "By allowing a driver to completely put away a smartphone while driving and making that phone controllable via the steering wheel and dashboard buttons and screens, the CCC creates a more responsible driving environment."

While the current MirrorLink mission is to limit driver distraction, the CCC said there are "some intriguing use cases when it comes to carrying the applications on your phone to other, larger displays so stay tuned for updates!" Life-sized Plants vs. Zombies on a big-screen TV? Fingers crossed!

Author's Note: How MirrorLink Works

One of the biggest challenges for a car reviewer these days is to differentiate all the vehicles we drive in a year. They're all pretty great anymore, and they're built to last more than cars ever were before. The scale pretty much goes from "good" to "great."

In-car electronics, though, are easy to compare, and they make a huge difference to consumers and journalists. The tricky part is knowing who the target audience for a car might be. Putting something like MirrorLink in a car your grandparents are going to buy will terrify them. Putting it in a car I might want to buy is a terrific idea. I love LCD screens. The more my car interior looks like the USS Enterprise, the happier I am.

There are in-dash displays that grow leaves, and LCD screens in the center console as big as the TV my family had when I was a tiny tot. The danger is in the distraction, but once we get those self-piloting cars online, we'll be golden. Welcome to the 21st century. It is awesome.
