Self-driving cars without steering wheels or pedals might have gotten a little bit closer to reality late last week. On Friday, the California Department of Motor Vehicles released a revised draft of regulations that could give more flexibility to autonomous car manufacturers than they have today. The proposed regulations allow testing driverless cars that pass a federal safety inspection, even with no driver in the car.

At the moment, states with self-driving car regulation normally require the presence of drivers. In California, 15 companies have permits to test vehicles as long as there is a licensed driver along for the ride, according to Reuters. On Thursday, Gov. Jerry Brown signed into law a bill for testing vehicles without steering wheels or pedals, but the pilot program only applies to vehicles traveling below 56 kph (35 mph) in a privately-owned business park.

In December, a year after a deadline set by state legislature, the California DMV released a first draft of regulation that would always require a driver’s presence at the steering wheel. Friday’s revision is a shift—allowing autonomous cars that pass a 15-point safety inspection by the National Highway Traffic Safety Administration to function without drivers.

The safety assessment would take into account the vehicle’s ability to avoid objects and pedestrians, cybersecurity, ethics, and backup plans if a system fails, for example.

The DMV is inviting interested members of the public to discuss the redrafted regulations during a workshop on 19 October in Sacramento.

If passed as law, the rules could potentially have implications for Alphabet (Google) and other self-driving car hopefuls, as the Associated Press reports. The Google Self-Driving Car Project has prototyped cars with only start and emergency stop buttons.

A spokesman for Google would not comment on the development.

We Need More Than Just Electric Vehicles

To decarbonize road transport we need to complement EVs with bikes, rail, city planning, and alternative energy

EVs have finally come of age. The total cost of purchasing and driving one—the cost of ownership—has fallen nearly to parity with a typical gasoline-fueled car. Scientists and engineers have extended the range of EVs by cramming ever more energy into their batteries, and vehicle-charging networks have expanded in many countries. In the United States, for example, there are more than 49,000 public charging stations, and it is now possible to drive an EV from New York to California using public charging networks.

With all this, consumers and policymakers alike are hopeful that society will soon greatly reduce its carbon emissions by replacing today’s cars with electric vehicles. Indeed, adopting electric vehicles will go a long way in helping to improve environmental outcomes. But EVs come with important weaknesses, and so people shouldn’t count on them alone to do the job, even for the transportation sector.
