General Motors (NYSE:GM) and AT&T (NYSE:T) are taking a huge technological leap this month, as GM begins offering 4G LTE connectivity in some of its models, starting with the 2015 Chevrolet Malibu. To put it in simpler terms, your car can now act as a rolling Wi-Fi hotspot, offering you high-speed Internet connectivity wherever you go.

The good news is that you won't have to take out a second mortgage to get GM's connectivity, which will be offered through its OnStar brand. AT&T is the lucky partner here, and General Motors is emphasizing a low-cost pricing model. It starts with a trial period of three months or 3 gigabytes, whichever comes first. After that, existing OnStar subscribers can connect for $5 per month for a 200 MB plan, up to $50 for 5 GB. Non-subscribers will pay from $10 to $50, depending on usage.

AT&T customers can add a GM vehicle to their Mobile Share Plan for $10 per month. Finally, General Motors is offering one-off packages to non-subscribers for as little as $5 per day.

What does all this actually look like within the vehicle? GM was showing off the technology at this year's International CES in Las Vegas. Our roving reporter Rex Moore was there, and he brought his camera inside the car for a demonstration.
