Very cool car tech startup

Circumnav Networks is one of the coolest startups I've seen in a long time. They are building a platform that collects speed and location data from cars, collates it, and then tells users the quickest route to their destination based on that data. The information should be much more granular than what Navteq can provide. And cars transmit this data to other cars opportunistically, using WiFi. It's very odd, very complex, and very interesting. I'll have a full Rafe's Radar writeup soon.
