GM requests green light to ditch steering wheel in its self-driving cars

Meet the Cruise AV Self-Driving Car

Climb into a self-driving car today and there’ll be a steering wheel right there where you’d expect, and probably a backup driver, too, ready to step in should something go awry during the journey. Not for long.

Cruise, the autonomous-car unit of  General Motors, wants to start testing its self-driving cars sans steering wheel. Indeed, it’s already produced a video (above) showing what such a design might look like.

Current National Highway Traffic Safety Administration (NHTSA) regulations, which were created at a time when self-driving cars were the stuff of science fiction, mean that vehicles have to include essential safety features such as a steering wheel and brake pedal. But the emergence of robot cars has put these rules under the spotlight.

According to a recent Reuters report, the NHTSA has confirmed it’s in talks with GM, which is asking for permission to test a limited number of autonomous cars without steering wheels or any other type of manual controls.

GM first raised the idea with the NHTSA at the beginning of 2018, and last week James Owens, the agency’s acting administrator, appeared to be warming to the idea.

“I expect we’re going to be able to move forward with these petitions soon — as soon as we can,” Owens told Reuters, adding that it would “definitely” arrive at a decision sometime next year. He described the removal of manual controls from a self-driving car as “a big deal” because it would be the first time for such action to be taken — marking a major milestone in the road to autonomous cars.

But U.S. Transportation Secretary Elaine Chao, who has been discussing GM’s petition with the NHTSA, sounded a note of caution, noting how on a number of occasions autonomous-car companies have had to reevaluate their ambitious plans. Even GM said recently that it would have to delay the launch of a proposed robo-taxi service because its technology isn’t quite ready.

“I think the complexity was far greater than what a lot of very optimistic advocates were thinking,” Chao told Reuters.


Waymo, another leader in the field of autonomous cars, has also asked the NHTSA to remove requirements for steering wheels.

“NHTSA should move promptly to remove barriers while ensuring safety,” Waymo said in a letter that was submitted over the summer as part of a public comment period on new rules for self-driving vehicles.

At the present time, autonomous vehicles use modified versions of existing manual models, such as Waymo’s Chrysler Pacifica Hybrid minivan, with the factory-installed steering wheels left in place. But in early tests of its technology, Alphabet-owned Waymo used a custom-built car dubbed the Firefly. The vehicle was originally designed without any manual controls, but Waymo had to add a steering wheel and brake pedal to comply with the current regulations.

Ditching the steering wheel and pedals would create additional space and allow for more creatively designed interiors. But the NHTSA needs to be satisfied that the technology is safe enough to allow for it to happen.

An autonomous car in San Francisco got stuck in wet concrete
A Cruise autonomous car.

A self-driving car operated by General Motors-backed Cruise got stuck on Tuesday when it drove into a patch of wet concrete.

The incident happened in San Francisco and occurred just days after California's Public Utilities Commission made a landmark decision when it voted to allow autonomous-car companies Cruise and Waymo to expand their paid ridesharing services in the city to all hours of the day instead of just quieter periods.

Six years after launching its autonomous-truck program, Waymo has said it’s decided to focus more on developing its ridesharing ambitions using its self-driving cars and minivans.

The California-based, Alphabet-owned company said its decision to effectively put autonomous trucking on the back burner is down to the “tremendous momentum and substantial commercial opportunity” that it’s seeing with the pilot ridesharing service it launched in Arizona in 2018 before taking it to several other states. Customers involved in the program can use an app to call a Waymo driverless car in the same way they would book an Uber.

Volkswagen is launching its own self-driving car testing program in the U.S.
Volkswagen self-driving ID. Buzz in Austin

Volkswagen is taking autonomous driving a little more seriously. While the likes of Tesla and Waymo have largely led the development of next-gen driving tech, the legacy automakers are certainly starting to invest more heavily. To that end, Volkswagen has announced its first autonomous driving program in the U.S.

As part of the program, Volkswagen has outfitted 10 all-electric ID. Buzz vans with autonomous driving tech, in partnership with autonomous car tech company MobileEye. Over the next few years, Volkswagen says it'll grow this fleet of autonomous cars to cover at least four additional cities, with the current fleet operating in Austin, Texas. By 2026, Volkswagen hopes to commercially launch autonomous cars in Austin.
