The National Highway Traffic Safety Administration (NHTSA) is considering whether it’s time to replace side and rear-view mirrors in cars with high-tech camera monitoring systems.

It’s not the first time the agency has studied the idea. In 2014, Tesla, Inc. and the Alliance of Automobile Manufacturers asked NHTSA to allow them to replace rear-view mirrors with cameras. The cameras would feed images of the rear of the vehicle onto a screen that would be positioned where the rearview mirror had traditionally been, or on the dashboard.

Now, NHTSA appears to be taking the idea more seriously. It recently asked for public comment on whether replacing mirrors completely would make motorists safer.
