General Motors is facing pushback over its request that U.S. regulators waive some automobile safety standards to make it possible to deploy a ride-sharing fleet of driverless cars without steering wheels or other human controls, according to an article by Reuters.

GM first made the request for a two-year temporary waiver on features like mirrors, dashboard warning lights and turn signals designed for a human driver in a petition filed with the National Highway Traffic Safety Administration (NHTSA) in January 2018, according to the article.

GM wants to deploy no more than 2,500 modified Chevrolet Bolt electric vehicles as part of a controlled on-demand ride-sharing fleet, likely to be based in San Francisco, by the end of 2019, according to the article.

Several groups raised concerns and pressed to require additional safety provisions or deny the petition outright.

The National Association of Mutual Insurance Companies said driverless vehicles without human controls should not be permitted on public roads until data proves the cars are safe, according to the article.

“NHTSA has no business enabling (automated vehicles) to operate on the roads, and surely has no business removing federally mandated vehicle safety standards to a vehicle that they do not know if it’s as safe as existing vehicles,” said the group, which represents 43 percent of U.S. auto insurers.
