Cadillac is beefing up the Super Cruise driver assistance system with several features, including automated lane changing. As such, your car will be able to change lanes on some highways under certain circumstances when you tap or fully latch the turn signal. The driver attention system will make sure you're focused on the car's surroundings while it's moving into a different lane.
Super Cruise will tell you when it's changing lanes or if it's unable to do so by itself. Cadillac will tap into LiDAR mapping, real-time GPS updates, camera system and radar sensors to determine which maneuvers are permitted on a particular stretch of road and whether it's safe to move into a different lane.
Cadillac's making several other changes to Super Cruise. It'll have more detailed map information that not only ensures the automated lane changes work, but to bolster functionality at highway interchanges and turns. The carmaker is also improving steering and speed control with the updated software, while making it easier and more intuitive for drivers to use the system.
