GMC

Several weeks ago, I was given a tour of Cadillac's new Mercedes E-class fighter, the XTS sedan. Until this week, I was allowed to put some miles on the car and to learn what Cadillac's CUE entertainment system achieves in a real-world setting.

P2P wireless technology is being explored to help people brake in time to avoid accidents.

It is obvious that GM is extremely proud of its CUE entertainment system interface. If you have some time to play with the system in the brag edition of the spanking new Cadillac XTS sedan, you immediately understand why.

The design's pretty arbitrary, and the ideas backing it are not quite imaginative. But the concept could be an inspiration for future PC cases.
