Car DVD players are not so rare nowadays. But why limit yourself to recorded videos? Now there’s a satellite dish you can stick on top of your car. TracVision gives you access to DirecTV satellite channels while you’re on the road, tracking satellites while you are in motion. It uses gyros and GPS to track the vehicle’s position and keep the signal. Hook it up to your in-car video system and your passengers can forget about playing punch buggy to keep themselves entertained. Current price for the equipment is $3,500, and maker KVH Industries is hoping to reduce that significantly in the years to come. But remember, it’s illegal to watch TV while you’re driving.
