US drops brake pedal requirement for self-driving cars

The National Highway Traffic Safety Administration (NHTSA) proposed Thursday that the government should 'end its requirement for self-driving vehicles to have manual brake pedals. This would make it easier to deploy such vehicles on U.S. highways.

The proposal does not apply to cars with a human driver. NHTSA has also stated that it will not abandon braking requirements for self-driving cars, such as strict standards on stopping distance.

The?agency has proposed a number changes to help facilitate the introduction of self-driving cars. NHTSA has begun developing "safety performance" tests for self driving vehicles, as part of an independent standard.

Automakers have expressed frustration with the slow pace of the agency's review of autonomous cars.

According to the law, self-driving cars do not require NHTSA approval?if they are equipped with human controls like steering wheels or brake pedals, or?mirrors.

NHTSA is authorized to grant petitions to allow up 2,500 vehicles per year to be operated on U.S. roadways without the need for human controls. However, it has spent many years reviewing petitions and has not taken any action.

The NHTSA announced last year that it would streamline the review of these exemption requests.

NHTSA asked for public comments in March on Amazon's self driving unit Zoox, which will deploy up to 2,500 specially-built robotaxis that do not require steering wheels.

In 2018, GM petitioned NHTSA for approval to deploy up 2,500 cars without brake pedals or steering wheels on U.S. highways, but then withdrawn the petition in 2020. Detroit's automaker asked NHTSA for approval in 2022 to deploy vehicles without human controls, but this petition was withdrawn in October 2024.

Separately on Thursday, NHTSA retracted a proposal from the Biden era to adopt a national voluntary framework?for evaluation and oversight?of?self driving vehicles.

Automakers expressed concern that the requirements were too strict, and some safety advocates argued it would not give NHTSA sufficient oversight to ensure a level of safety appropriate.
