Look, Ma, no hands: Cadillac's new Super Cruise semi-autonomous driving system

Cadillac is in the middle of a massive marketing campaign to introduce its new Super Cruise. The semi-autonomous driving system, available only on the CT6 luxury sedan, is being billed as offering the "first true hands-free driving on the freeway." The car company has sent CT6 sedans literally across the country, holding events in multiple U.S. cities, offering auto journalists short Super Cruise seminars followed by a turn behind the wheel. The system is highly sophisticated. Using a combination of Lidar, high-resolution GPS and a Driver Attention System that monitors the driver, Super Cruise will allow the car -- on certain roads, under certain conditions -- to travel great distances without any steering wheel input by its operator.
