Feel like the Internet is following you around like a horde of zombies? Slowly but surely, it's spreading everywhere....including your car. A number of manufacturers -- among them Audi, Ford, Subaru, GM and Chrysler -- now offer systems that turn vehicles into mobile Wi-Fi hotspots, making use of a 3G cellular network. While some might decry the innovation, we say relax and join the Internet zombie horde. The ability to view websites, check status updates and respond to emails on the road will make it well worth your while. Remember, it's better to ingest information than brains.
