General Motors has treaded carefully with the rollout of its semi-autonomous system called Super Cruise. Until now, GM’s only made it available on the most recent Cadillac CT6s, but now the automaker is planning to expand it beyond Cadillac after 2020 and eventually to all of its U.S. brands, .

The news came by way of GM’s product chief, Mark Reuss, and it’s the first time the automaker has provided a timeframe to expand the system beyond Cadillac.

Here’s more from :

Reuss, during a presentation at the Intelligent Transportation Society of America conference, also announced plans to offer vehicle-to-everything (V2X) communications in a high-volume Cadillac crossover by 2023. That technology, he said, also will eventually expand across the brand’s portfolio.

“These announcements demonstrate both our intention to lead in technical innovation, and Cadillac’s place at the tip of the corporate spear when it comes to rolling out that innovation,” Reuss said.

It’s a big move for GM. When I reviewed Super Cruise last fall I described it as a plainly safe utilization of semi-autonomous technology. Relying on 130,000 miles of mapping data in the U.S. and Canada, along with a suite of sensors and high precision GPS, GM only allows Super Cruise to be used on limited-access freeways with a divider, and with defined on and off-ramps.

A camera on the steering wheel is super unnerving—who likes the feeling of being watched at all times?—but it makes it impossible to peel your eyes away from the road, unlike Tesla’s Autopilot, which gives drivers . (Tesla’s under investigation for several crashes involving cars that had Autopilot deployed at the time.)

We’ve quarreled over which system is better——but the hyper-conservative approach of Super Cruise works, . It works as GM markets it, and that’s a good thing. In a world where consumers are skeptical of autonomous driving, it’s a smart way to adapt people to the idea of letting a car drive itself one day. Putting the system in every model only helps make that goal a reality.
