https://www.forbes.com - We knew this was coming. Level 3 autonomous driving is here. It is thrilling and terrifying, and it’s available on the 2018 Cadillac CT6 full-size sedan. I got a chance to take a long test drive with Super Cruise, as Cadillac calls their system. We took a two-day drive from Santa Fe, New Mexico to Los Angeles, California. I returned with a healthy dose of respect for the incredible engineering achievement of the Cadillac team, and a severe case of terror that Super Cruise (or any other system like it) should be implemented into the current traffic environment.
