Imagine what google-watchers will have to say about Google knowing where you've been driving!

I wonder what they'll offer...will it project 3D maps on a heads-up display? Or maybe project arrows in your line of sight directing you where to go. Could be cool, could also be too much to handle for some people :)

Or maybe it will just offer what your basic GPS offers now.

“So can I get free gas if I run AdWords on my bumper?”

Only if someone clicks on the ad. :)
