Scott Jagow: Last week was all about gadgets, with the Consumer Electronics Show in Vegas. This week, it's cars. Big auto show got rolling this morning in Detroit.

Jim Kliesch: It could be 20 years for some of the technology, but a number of the automakers are showing some of the nearer-term technology that's going to be on the roads in the not too distant future.
