Might also work for DARPA autonomous vehicle race
Apparently there have already been successful cross-country robotic vehicles. But from what I've read they use lasers to scan the terrain ahead, create a 3D contour map, overlay color & contrast data to identify the roadway, and then drive forward. Very computationaly intensive.

Birds bob their up & down, left & right, to figure out what's close and what's far away. Close objects move around more in their visual field. We use stereoscopic vision to do the same without bobbing our heads around. I bet this could be used to program a computer to drive a car.
