This is why EVDO cellular internet is cool: the guys from EVDOInfo.com rigged together a little application using off the shelf parts to display on a web page their car, its exact location and velocity, as well as the current view out their window. It’s tricks like these that will make EVDO (and UMTS, if Cingular ever gets it deployed) a standard feature for “carputers” before long.

And to think, just a few short years ago these technologies were reserved for child molesters and enemies of the state.
