US regulators move a step closer to recalling Tesla vehicles with Autopilot automated driving systems

Teslas with semi-autonomous driving systems are one step closer to being recalled

After the US stepped up its inquiry into a number of crashes with parked emergency vehicles or trucks with warning signals.

The National Highway Traffic Safety Administration (NHTSA) announced on Thursday that the Tesla investigation has been upgraded to an engineering analysis

Indicating that the electric vehicle maker and automated systems that conduct at least some driving responsibilities are being scrutinised more closely.

Documents posted on Thursday by the US agency raise some serious issues about Tesla's Autopilot system.

The agency discovered that it was being utilised in regions where its capabilities were limited

That many drivers were failing to take action to avoid collisions despite the vehicle's warnings.

The investigation has now expanded to include practically all of the Austin

Texas-based automaker's vehicles sold in the United States since the start of the 2014 model year.

After a series of collisions involving Teslas using the company's Autopilot or Traffic Aware Cruise Control systems since 2018

NHTSA launched an investigation in August of last year after first responders deployed flashing lights, flares, an illuminated arrow board, or cones to warn of hazards.
