Recent revisions to the proposed rules, which were released late last month, include a requirement that companies "self-certify" that their vehicles meet both federal vehicle safety standards and the National Highway Traffic Safety Administration's guidelines for autonomous vehicles.
Manufacturers must also obtain an ordinance or resolution from local authorities that specify the roadways, speeds and other conditions that their vehicles are designed to operate in to ensure that communities have input on where testing occurs, the DMV said in a notice issued in September.
DMV officials who attended the workshop in Sacramento heard from technology, legal and transportation experts.
Though representatives from companies such as Ford Motor Co. and Google said the proposed rules were an improvement over the first set of draft regulations released in December, several expressed concern about potential overlap with federal laws.
