Teslas with partially automated driving systems are a step closer to being recalled after the U.S. elevated its investigation into a series of collisions with parked emergency vehicles or trucks with warning signs.The National Highway Traffic Safety Administration said Thursday that it is upgrading the Tesla probe to an engineering analysis, another sign of increased scrutiny of the electric vehicle maker and automated systems that perform at least some driving tasks.An engineering analysis is the final stage of an investigation, and in most cases NHTSA decides within a year if there should be a recall or the probe should be closed.Documents posted Thursday by the agency raise some serious issues about Tesla’s Autopilot system. The agency found that it’s being used in areas where its capabilities are limited, and that many drivers aren’t taking action to avoid crashes despite warnings from the vehicle.The probe now covers 830,000 vehicles, almost everything that the Austin, Texas, carmaker has sold in the U.S. since the start of the 2014 model year.NHTSA reported that it has found 16 crashes into emergency vehicles and trucks with warning signs, causing 15 injuries and one death.Investigators will evaluate additional data, vehicle performance and “explore the degree to which Autopilot and associated Tesla systems may exacerbate human factors or behavioral safety risks undermining the effectiveness of the driver’s supervision,” the agency said.A message was left Thursday seeking comment from Tesla.In the majority of the 16 crashes, the Teslas issued forward collision alerts to the drivers just before impact.

An engineering analysis is the final stage of an investigation, and in most cases NHTSA decides within a year if there should be a recall or the probe should be closed.
Documents posted Thursday by the agency raise some serious issues about Tesla’s Autopilot system. The agency found that it’s being used in areas where its capabilities are limited, and that many drivers aren’t taking action to avoid crashes despite warnings from the vehicle.
The probe now covers 830,000 vehicles, almost everything that the Austin, Texas, carmaker has sold in the U.S. since the start of the 2014 model year.
NHTSA reported that it has found 16 crashes into emergency vehicles and trucks with warning signs, causing 15 injuries and one death.
Investigators will evaluate additional data, vehicle performance and “explore the degree to which Autopilot and associated Tesla systems may exacerbate human factors or behavioral safety risks undermining the effectiveness of the driver’s supervision,” the agency said.
A message was left Thursday seeking comment from Tesla.
In the majority of the 16 crashes, the Teslas issued forward collision alerts to the drivers just before impact. Automatic emergency braking intervened to at least slow the cars in about half the cases. On average, Autopilot gave up control of the Teslas less than a second before the crash, NHTSA said in documents detailing the probe.
NHTSA also said it’s looking into crashes involving similar patterns that did not include emergency vehicles or trucks with warning signs.
The agency found that in many cases, drivers had their hands on the steering wheel as Tesla requires, yet they failed to take action to avoid a crash. This suggests that drivers are complying with Tesla’s system that makes them keep hands on the wheel, the agency wrote. Yet this doesn’t necessarily make sure they’re paying attention.
In crashes were video is available, drivers should have seen first responder vehicles an average of eight seconds before impact, the agency wrote.
The agency will have to decide if there is a safety defect with Autopilot before pursuing a recall.

Investigators also wrote that a driver’s use or misuse of the driver monitoring system “or operation of a vehicle in an unintended manner does not necessarily preclude a system defect.”
The agency document all but says Tesla’s method of making sure drivers pay attention isn’t good enough and that is a safety defect that should be recalled, said Bryant Walker Smith, a University of South Carolina law professor who studies automated vehicles.
