GM Super Cruise Network Jumps From 400 to 750k Miles, Includes Lots of Minor Highways

It was April 2013, more than a decade ago, when General Motors first announced the planned development of Super Cruise, an autonomous driving technology. It was known as a completely hands-free system, allowing drivers to take their hands off the wheel entirely and feet off the pedals (their attention level is monitored, though) since the summer of 2015, but it was another couple of years before the feature premiered on the 2018 Cadillac CT6.

In 2019, the system had a first expansion worth some 70k miles (about 113,000 km), allowing drivers to take advantage of the Super Cruise on around 200k total miles (almost 322,000 km) of compatible highways in the United States and Canada. Since 2020, the company has also started expanding the system's reach to CT4 and CT5 plus Escalade models from Cadillac.

Today, there are more and more models from GM brands with Super Cruise – including GMC Hummer EV, Cadillac XT6 and Lyriq, Chevrolet Bolt EUV, Buick Envision, and the upcoming Caddy Escalade IQ, among others. The company also wants to be a leader in hands-free driving technology – making it a direct competitor to Tesla's FSD, focusing on expanding features (like introducing optional trailering) and adding more drivable roads.

More precisely, the latest progress has jumped the network's tally of roads from around 400k to approximately 750k miles in the United States and Canada, with GM saying that's thrice the distance from Earth to the Moon or a coast-to-coast roundtrip from New York City to San Francisco about 130 times! More importantly, the new expansion covers a lot of smaller highways that usually connect minor cities and townships.

This also means Super Cruise on models like the 2024 Chevrolet Traverse or 2024 GMC Acadia will take full advantage of the trailering mode when using their compatible trailers for camping, boating, or other recreational activities. To date, GM says that more than "160 million miles (257 million kilometers) have been driven accident-free with Super Cruise," thanks in part to the latest batch of new or enhanced features like Automatic Lane Change and Lane Change on Demand, Enhanced Navigation, industry-first Hands-Free Trailering, Collaborative Steering, Enhanced Driver Requested Offset, or Improved Curve Handling.

The expansion is already rolling out to compatible vehicles as an over-the-air software update (free of charge) and will be available to every model until and through 2025. However, some minor exceptions exist – the upgrade is not arriving on the Cadillac CT6, Chevrolet Bolt EUV, and Cadillac XT6.
