GM faces pushback on U.S. self-driving vehicle plan

The largest U.S. automaker said it hoped 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.

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…

In March, NHTSA made the petition available for public comment for the 60 days that ended on Monday.

Several groups, including car dealers and insurers, raised questions posted publicly this week pressing NHTSA to demand more data, 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.
