GM Expands Super Cruise Road Network To 400,000 Miles


Not many car enthusiasts will be happy to hear this, but casual vehicle customers will probably be pleased to know that General Motors makes hands-free driving available to most public road networks in the United States and Canada. The automaker announced it will add new roads to the existing Super Cruise road network soon, essentially doubling its range from 200,000 to 400,000 miles.

Currently, the self-driving assistance system is working on pre-mapped highways and the new expansion will add additional state and federal routes, combining undivided and divided highways. Here are some important new routes added to the Super Cruise road network:

  • Mother’s Road – US Route 66
  • Pacific Coast Highway – CA Route 1
  • Overseas Highway – US Route 1
  • Trans-Canada Highway

Updates to the Super Cruise will be available for vehicles based on the Vehicle Intelligence Platform (VIP), including the Cadillac Escalade, CT4, and CT5, GMC Hummer, and Chevrolet Silverado and Sierra. The new software will hit cars as it is produced with existing fleets expected to receive over-the-air updates (OTA updates) for free “later this year.” Meanwhile, Super Cruise technology will soon be available on the Chevy Tahoe and Suburban, as well as the GMC Yukon and Cadillac Lyriq.

GM said it would continue to add new avenues to the Super Cruise network with help from Usher, a company that does LIDAR mapping for automakers. The manufacturer is in communication with the Department of Transportation and when there is a road change, GM will be notified and map the section again. Until the road is remapped, the system won’t work on that spot, handing control to the previous driver. On the mapped road, Super Cruise hands control back to the driver 350 meters before the intersection and 500 meters in a non-VIP architecture vehicle.

Super Cruise is GM’s first self-driving assist technology that accelerates, brakes, maintains lane position, and changes lanes (on some models) to pass slower traffic. LIDAR map data, real-time cameras, radar and GPS are responsible for keeping the vehicle centered on the lane without any input from the driver.

“GM stands ready when it comes to advanced accessible driver assistance technology. We’re adding Super Cruise to more vehicles than ever before, and on more roads for more customers to enjoy,” said Mario Maiorana, GM chief engineer, Super Cruise. pursuing what we believe is the most comprehensive path to autonomy in the industry with the adoption of responsible automated driving technologies such as Super Cruise at the core of what we do.”
