By doubling the Super Cruise road network, hundreds of thousands of additional miles of roads in the U.S. and Canada can be explored hands-free. Super Cruise currently works on mapped divided highways, known as interstates. This expansion will enable Super Cruise to work on many additional state and federal routes, a combination of undivided and divided highway roads. We are adding Super Cruise to more vehicles than ever, and on more roads for more customers to experience,” said Mario Maiorana, GM chief engineer, Super Cruise.
