Google and a cadre of automakers are not happy about the state of California's proposed rules for autonomous vehicles, which they say would severely slow their progress towards a self-driving future. Although the state legislature approved autonomous trials last month, the group objected to the state's decision to require certain regulations that the federal government made voluntary it its own policy. The group of tech and car companies protesting the regulations includes General Motors, Volkswagen, Honda and Ford, as well as the Self-Driving Coalition for Safer Streets, which counts Google, Lyft, Uber and Volvo among its members. According to Reuters, the group laid out its concerns during a hearing in Sacramento this week and mainly objected to the state's decision to require a new autonomous vehicle data recorder. They also objected to giving police the ability to request self-driving data without a warrant or a subpoena, and a separate proposal that they claim would force them to wait an entire year between testing a new vehicle and getting it rolling on public streets.
