General Motors announced on Wednesday that its Super Cruise semi self-driving system will soon proliferate across the automaker's other brands. The system first debuted with the 2018 Cadillac CT6 and is able to handle most driving functions on divided freeways. After 2020, GM said the system will be available on every single Cadillac before it begins to roll out to other GM brands.
