GM’s hands-free driver assistance system Super Cruise, has been lauded for its capabilities. But it’s also been criticized because of its severe limitations. So far, it’s only available in one Cadillac model, the full-size CT6 sedan, and its use is restricted to certain divided highways.

GM’s luxury brand Cadillac said Wednesday that it is expanding Super Cruise through a software update that will add another 70,000 miles of compatible divided highways in the United States and Canada. By the end of the year, Super Cruise will be available on more than 200,000 miles of highways.
