The U.S. National Highway Traffic Safety Administration is holding talks with General Motors Co. on the automaker’s petition to deploy a limited number of self-driving vehicles on American roads without 
steering wheels or other human controls, the head of the agency 
said Friday. Acting NHTSA Administrator James Owens said his agency aims to decide soon on GM’s January 2018 petition as well as on a request by Nuro, a driverless delivery startup backed by Softbank Corp., to deploy a limited number of low-speed, highly automated delivery vehicles without human occupants. The agency’s review comes at a time of heightened concerns 
about the safety of automated piloting systems in vehicles and 
aircraft, a potential revolution in ground and air transportation. “I expect we’re going to be able to move forward with these 
petitions soon — as soon as we can,” Owens told Reuters, adding 
action “definitely” would come next year. “This will be a big deal because this will be the first such action that will be taken,” Owens said. GM, the No. 1 U.S. automaker, confirmed it has been in talks with NHTSA about the petition. Nuro also confirmed it is in talks with NHTSA. Still work to doGM Chief Executive Mary Barra and U.S. Transportation Secretary Elaine Chao last week met and discussed the petition, officials said, but significant work remains at the technical level. Owens said NHTSA officials are “crawling through these petitions because we want to make sure” the driverless vehicles are at least as safe as other cars on the roads. “There’s a lot of back and forth between us and the companies,” Owens said during a Reuters interview that also included Chao and other Transportation Department officials. “We’re sharing with them thoughts and ideas and concerns. They come back to us with additional information.” Chao said it is important that NHTSA take its time in reviewing the GM petition. Chao suggested that some auto industry officials and analysts were too optimistic about the timing for deployment of fully autonomous vehicles. “I think the complexity was far greater than what a lot of very optimistic advocates were thinking,” Chao said.  FILE – In this Aug. 16, 2018, photo a self-driving Nuro vehicle parks outside a Fry’s supermarket, which is owned by Kroger, as part of a pilot program for grocery deliveries in Scottsdale, Ariz.In GM’s petition, NHTSA is for the first time looking at a vehicle in which all driving decisions are made by a computer rather than a human driver. Nuro, which partnered with Kroger Co. last year to deliver groceries, seeks approval not to include a windshield in the vehicle. The petitions — formal applications for action by the agency — seek exemptions from U.S. vehicle safety rules largely written decades ago that assumed human drivers would be in control of a vehicle. The petitions are for up to 2,500 vehicles per manufacturer. GM initially said it hoped to win approval to deploy the vehicles by the end of this year. But in July its self-driving unit, Cruise, said it was delaying commercial deployment of cars as more testing of the vehicles was required. A new target date wasn’t specified. Alphabet Inc.’s Waymo unit this year began offering some rides with no human driver in its limited autonomous ride-hailing service in Arizona, but with steering wheels and employees watching remote feeds of the vehicles’ cameras. “We’re in communication with them about how they are ensuring the safe operation of the vehicle,” Owens said. “We will continue having a back-and-forth with them.”
