Dive Brief: General Motors says it's charting a path toward “personal autonomy” that includes hands-free highway driving as the automaker prepares to roll out Super Cruise to its highest-volume models in North America, the company announced in a press release.

To scale a full autonomous driving stack in future vehicles, GM developed a next-generation central compute and zonal electrical architecture that it calls a “radical departure from traditional automotive electronics.”

This level of flexibility allows GM to avoid having to re-engineer systems for every trim and body style in its portfolio and more easily scale Super Cruise.

Future GM vehicles will also collect data used to improve autonomous driving technology over time.

GM is further improving Super Cruise in the safety of a computer-simulated environment built from real-world data.
