The new system marks a collaboration between the team responsible for General Motors' eight-year-old Super Cruise, an advanced driver-assistance system that the automaker today described as “hands-free” on some highways, and Cruise, a robotaxi subsidiary that once competed with Waymo before GM cut off its funding in 2024. It could also put the Detroit automaker in contention with other automakers—Toyota and Tesla among them—who are trying to bring some version of self-driving systems to drivers’ personally owned cars.
