3. Europe's Anti-Red Light App
Availability: Several years/not nearly soon enough
The Compass4D program is an ongoing European traffic project focused on intersections, but the fact that it's adorably buried under the heading "Energy Efficient Intersections" is a little tidbit on an already-in-testing app. It's hooked up to the traffic light system, and it can recognize when a red light makes no sense, so it can change a red to a green. It's really for emergency vehicles and large trucks, but still, that traffic signal alchemy you always dreamed of is real, and will actually be here some day.
4. The Transparent Cockpit
Availability: Closer than you'd think
Yep. You're looking at an invisible car...kind of. A group of media design professors in Japan have been working on a way to essentially sidestep the laws of physics and create what they've called a transparent cockpit. Cameras on the outside of the car are paired to crazy advanced projectors on the inside which create the illusion that you're looking through the body work. It's not just a parlor trick; the idea is that you will eventually see things like a kid or a dog that you wouldn't otherwise notice.
