GM has added a new group of highways to its hands-free driving technology Super Cruise, expanding the reach of the Super Cruise network to around 750,000 miles (1.2 million kilometers) of road across the U.S. and Canada. The network itself encompasses various road types, including divided, major, and minor highways. Through this expansion, GM is aiming to support the safe deployment and expansion of ADAS, while also encouraging consumer trust in ADAS like Super Cruise.

GM first launched Super Cruise in 2017 and has continued to expand its Super Cruise network since then – most recently to 400,000 miles (640,000 kilometers) to include major Canadian, U.S. and state highways. Since its launch, GM has added and enhanced a variety of features including Lane Change on Demand, Automatic Lane Change, Hands-Free Trailering, and Improved Curve Handling.

This latest expansion adds minor highways that typically connect smaller cities and townships. In adding these highways to the network, GM envisions its customers using hands-free driving between more rural towns across the U.S., with a particular emphasis on its customers travelling with compatible trailers for camp or boating and using recreational vehicles.

GM confirmed that the new group of highways are currently being added incrementally over-the-air and will continue to be added through 2025 at no extra cost. While the majority of vehicles equipped with Super Cruise will receive this expansion, the Cadillac CT6, Cadillac XT6, and Chevrolet Bolt EUV will not be receiving these updates.
