According to Cruise's X(Twitter) account [0], the suspension seems to be related to an incident in which a human driver hit-and-run propelled a pedestrian in front of a Cruise AV and the Cruise vehicle couldn't avoid hitting the person. When that incident was first reported [1], it seemed like a situation where if it was a human driver in the Cruise vehicle, they wouldn't be found to be at any fault. However given this suspension, I wonder if there's more to it than that.
