Verizon just rolled out its 4G LTE wireless broadband network, and with General Motors using Big Red for its OnStar system for over 15 years, GM is asking itself: What can we do with all this bandwidth?

The answer is 'plenty'... but nothing immediately.

Instead, GM and Verizon equipped a Buick LaCrosse with a 4G LTE modem and a host of cameras, sensors and controls and is trotting it out at CES to demonstrate how the broadband tech could be implemented.

Among the possible applications is a vehicle monitoring system that utilizes a handful of lipstick cameras to transmit video to the driver to see what's going on both inside and outside the vehicle while they're away. On the same front, the system can be paired with Verizon's 4Home service, which connects with home security cameras, lights and thermostats and transmits information back to the driver.

Other features include voice search, a traffic view that streams live traffic-cam images, Skype with video chat and a impact detection system that would identify if your car was hit in a parking lot, and would then turn on all the exterior cameras and capture an image of the offending vehicle as it drove away.

We'll be checking the system out later this week, so stay tuned for our initial impressions from CES.
