Cadillac to expand Super Cruise highway network, adding 70,000 milesby Justin King
The additional highways are located in the US and Canada.
General Motors has announced a significant expansion in the range of roads that will work with Cadillac's Super Cruise technology.
Until now, Super Cruise has been limited to approximately 130,000 miles of limited-access divided highways. The company is now adding another 70,000 miles of highway, located in the US and Canada.
Super Cruise relies on lidar map data and high-precision GPS, barring drivers from using the hands-free driving system on roads that have not been fully mapped.
For now, owners of 2018- and 2019-model-year Cadillac CT6 sedans must bring their car to a dealer to enable the additional miles. Eventually, GM will deploy an over-the-air update system that will eliminate the need for a dealer visit.
