The 2010 Toyota Prius gets 50mpg while bringing dead trees back to life. But maybe more our speed, the car also features a really nifty "Tracer Display" unlike anything we've seen in dashboards before.

It's a simple idea: You control car functions (like the stereo) with buttons on the wheel while the Tracer Display superimposes these buttons over your dashboard display. In other words, you can keep an eye on your speedometer instead of your wheel while searching for the one radio station not playing commercials.

And even though this display is a bit blurry in this shot, you can tell that the graphic overlay is really quite bright and sharp. Neat if Prius owners needed another reason to be so smug. [KickingTires, Jalopnik]
