A Toyota official on Tuesday raised concerns about California's plans to require compliance with a planned U.S. autonomous vehicle safety check list, calling it "preposterous." Reuters reports:Hilary Cain, director of technology and innovation policy at Toyota Motor North America, criticized California's proposal to require automakers to submit the U.S. National Highway Traffic Safety Administration's (NHTSA) 15-point safety check list before testing vehicles. "If we don't do what's being asked of us voluntarily by NHTSA, we cannot test an automated system in the state of California. That is preposterous and that means testing that is happening today could be halted and that means testing that is about to be started could be delayed," she said at a Capitol Hill forum. On September 30, California unveiled revised rules that carmakers will have to certify that they complied with the 15-point NHTSA assessment instead of self-driving cars being required to be tested by a third-party, as in the original proposal.
