Finally, an a car navigation system that I might consider using. The “Dash Express” link cars together over wireless and cellular networks to provide real traffic condition information. It sounds like only a few cars with the device are needed to provide traffic data, though, I imagine the more cars on the network the better. I wonder, though, can they get enough users to make this viable and I wonder why they didn’t license the technology to companies such as Garmin that already have a stong present in mobile GPS. It would be much easier for me to part with $400 for something I know other people will eventually buy than to take a chance on a start-up company that is challenging a fortified hill. There’s a video embedded in the article, so here’s a link back to the orginal article.
