U.S. transportation officials are considering a new class of motor vehicles — ones with no occupants — in preparation for an expected surge in robot deliveries of everything from groceries to pizza.

Why it matters: Unmanned delivery vehicles are different from self-driving passenger cars, but both require exemptions from federal motor vehicle safety standards (FMVSS) in order to operate on public roads.

  • Carving out a new class for delivery robocars would be a step toward defining standards for future automated vehicles.

Where it stands: DOT is reviewing petitions from 2 companies — GM and Nuro — for exemptions from FMVSS.

  • GM's Cruise subsidiary wants permission to deploy a fleet of robotaxis with no steering wheels or pedals in San Francisco.
  • AV startup Nuro is seeking large-scale deployment of its compact delivery vehicles, currently in pilot phase with Kroger and Domino's.

Of note: A DOT official tells Axios the agency will consider updating the standards on a case-by-case basis, but says a simpler approach could be to create a new motor vehicle class for AVs.

Between the lines: Nuro is the perfect test case.

  • Vehicle safety standards were created with human drivers in mind. But, in Nuro's case, there are no occupants at all — so things like seat belts, backup cameras and mirrors don’t apply.
  • The vehicles are equipped with lidar and camera sensors that provide a 360-degree view.
  • If DOT were to approve an exemption for Nuro's R2X model, it could generate data that would help regulators develop standards for a new class of unmanned delivery vehicles, the DOT official said.

Background: There is a precedent — 20 years ago, as electric golf carts grew popular on subdivision streets, NHTSA created a new motor vehicle class for low speed vehicles.

  • Those low-speed vehicles are now the basis for limited AV passenger shuttles run by companies such as May Mobility and Optimus Ride.

The bottom line: DOT's goal is creating standards that ensure safety but can accommodate new technologies over time.

Joe Biden explained on Twitter Thursday night what he "meant" by earlier comments suggesting that "the African American community is a monolith."

What they're saying: "Unlike the African-American community, with notable exceptions, the Latino community is an incredibly diverse community with incredibly different attitudes about different things," Biden remarked in an interview hosted by the National Association of Hispanic Journalists and the National Association for Black Journalists, Politico reports.
