Great GPS Nav Visualization

This in-car navigation visualization looks like a terrific idea. It's simple, heads-up, and will work in the dark. So far it seems to exist in demo-only form but if it works in on-the-road conditions it will be much better than in-dash systems which require the driver to look away from the road, thus dividing attention. Additionally, existing systems need the driver to correlate the suggested route with a visualization of the route. This system would overlay the route on the actual environment! Couple the red line visualization with voice directions (which already exist in GPS nav in-car systems) and this looks like a winner.
