GM’s Super Cruise is getting a lot more useful as the company has announced the hands-free semi-autonomous driving system will be able to operate on approximately 750,000 miles (1.2 million km) of compatible roads in the United States and Canada. This is nearly twice as much as the previous distance of 400,000 miles (643,738 km).

That’s a stunning number and GM noted it’s the equivalent of “traveling one way from Earth to the Moon three times or taking a coast-to-coast road trip from New York City to San Francisco and back nearly 130 times.” On top of that, the company said Super Cruise has nearly six times the coverage area as competitors.

Needless to say, Super Cruise has come a long way since it launched in 2017. The company has been expanding coverage ever since then and the latest update focuses on “minor highways that typically connect smaller cities and townships.” It follows an expansion in 2022 that targeted major state and federal highways in the United States as well as key Canadian corridors.

GM didn’t go into many specifics, but the latest expansion won’t be fully complete until next year. That being said, the company noted “new roads have already started to be added incrementally over-the-air, at no additional charge, and will continue to be added through 2025.” The automaker also revealed the Chevrolet Bolt EUV, Cadillac CT6, and Cadillac XT6 won’t benefit from the expansion.

That’s unfortunate, but GM said customers have driven more than 160 million miles (257 million kilometers) accident-free with Super Cruise and more than 80% of owners said the system “makes driving more relaxing.”
