One such system is called the Dash Express. Using technologies such as GPS, GPRS cellular and Wi-Fi, allows it to constantly update traffic conditions based on the speed and locations of other cars with the Dash Express.
Other features include e-mail, an SMS message that describes the best way to get to work and what time you need to leave. The system is constantly updated by Yahoo! Local.
Dash has set the release of this new system for early 2008. Other GPS navigation device manufacturers like Garmin and Magellan are working on the same concepts.
