Road safety agency opens evaluation over reported collisions in low visibility

The US government’s road safety agency has opened an investigation into 2.4m Tesla vehicles with the automaker’s Full Self-Driving software after four reported collisions, including a fatal crash.

The National Highway Traffic Safety Administration (NHTSA) on Friday said it was opening the preliminary evaluation after four reports of crashes where Full Self-Driving was engaged during reduced roadway visibility like sun glare, fog or airborne dust.
