Google representatives said Tuesday that they want regulation on self-driving cars to follow the basic model used on conventional cars — a self-reported analysis that does not include additional oversight by the California Department of Motor Vehicles. The perspective arrives as the DMV considers what safety rules it will impose on self-driving cars, which could be released to the public in less than a decade. At a DMV-hosted public workshop last month, Google warned regulators that safety oversight above what is applied on conventional cars could be ineffective and hurt innovation.
