General Motors’ autonomous car unit, Cruise, announced on X Thursday night that all its driverless car fleets nationwide will be halted after several collisions and a suspension of its license in California.

“The most important thing for us right now is to take steps to rebuild public trust. Part of this involves taking a hard look inwards and at how we do work at Cruise, even if it means doing things that are uncomfortable or difficult,” Cruise wrote in a post.

The San Francisco-based company continued, “In that spirit, we have decided to proactively pause driverless operations across all of our fleets while we take time to examine our processes, systems, and tools and reflect on how we can better operate in a way that will earn public trust.”

Cruise explained that pausing its driverless car fleets was not “related to any new on-road incidents, and supervised AV operations will continue,” adding, “We think it’s the right thing to do during a period when we need to be extra vigilant when it comes to risk, relentlessly focused on safety, & taking steps to rebuild public trust.”
