A press release on Friday from Volkswagen talks about a plan between the car maker, nVidia, and Google Earth to produce a new navigational system prototype that shows terrain in 3D with mapped orthophotos such that drivers can see from their point of view what things should look like.

Interesting plan from a technological proof of concept, but I'm not sure how useful it will be for drivers in real-world situations. I understand the idea that seeing exactly what's in front of you might be beneficial, but if it's going to be low resolution or distorted, I think a less cluttered view is more useful.
