California regulators on Wednesday rolled out the latest proposed rules for regulating driverless cars, staking their claim for strong state oversight in the face of increased calls for federal preemption.

The new rules for testing and deployment made mostly minor changes to draft regulations released in March. There’s more clarity about notifying cities and counties about testing driverless cars. There’s a standard template now, too, for manufacturers to report incidents when a car’s autonomous-driving features were disengaged.
