The big auto show in Detroit doesn't kick off until next week, but major car companies are already showing off some of their more exciting car-tech prototypes here at the International Consumer Electronics Show. BMW and Audi unveiled their latest driverless car technology and conducted demonstration drives. Nevada is one of a few states where it's legal to test drive autonomous cars, though it requires a person to sit in the driver's seat at all times. BMW added its highly active assist technology to a modified 2 Series Coupe. The car can slide into a controlled drift to demonstrate how precise the control systems are and how it can handle a critical situation. The company has posted a video showing it in action.
