What makes a digital car digital?

Driving can be a lot simpler if you know where you’re going. Like K.I.T.T., digital cars have navigation systems — and these onboard guides are about to get even more sophisticated. Next-generation onboard navigational systems will have 3-D overviews of your route and destination. Soon, you’ll be able to get real-time traffic reports from other drivers; ultimately, navigation systems may become a wireless network of cars sending information to one another [source: CNet]. As this information database is expanded and updated in real time, your navigation system will even be able to guide you to the gas station with the cheapest fuel.

These cars aren’t just guiding drivers over long stretches of road. Another high-tech feature, auto valet, uses satellite images to guide you into parking spaces — even tight parallel spots. Once you enable the electric power steering, just sit back: The car uses sensors to detect objects around it and powers the car to pull smoothly into your chosen space. No hands, literally [source: New York Times].
