Here's how Cadillac's semi-autonomous Celestiq will work

The $300,000 Cadillac Celestiq is the brand's bid to reclaim the "Standard of the World" title, and it will be equipped with what General Motors thinks will be the best driver assistance technology. The sleek, electric four-door will be the first GM product to feature Ultra Cruise, which is a step above the Super Cruise system that's available today and is being developed to provide hands-off driving on most roads 95% of the time. Super Cruise offers hands-off driving on 400,000 miles of pre-certified highways using radars, cameras, GPS and hyper-accurate maps while facial recognition tech ensures the driver is paying attention and ready to take control when required. Jason Ditman, Ultra Cruise chief engineer, said that Ultra Cruise will have a forward-looking lidar unit mounted behind the windshield that work along with both short-range and long-range radars, long range cameras and over 20 sensors in total to provide full coverage of what's around the car. The Celestiq's lidar will be installed behind the windshield.
