NHTSA reveals crash clampdown on autonomous and driver-assis

US road safety regulators are set to dramatically increase the reporting requirements for car crashes where driver-assistance tech like Tesla Autopilot was engaged at the time, the NHTSA confirmed today. Under the new policy, serious incidents involving vehicles equipped with SAE Level 2 advanced driver assistance systems (ADAS), or SAE Levels 3-5 automated driving systems (ADS), will need to be reported to the agency.

By the SAE definitions, Level 2 includes autonomous cruise ซุปเปอร์ สล็อต control and lane-keeping assistance, features increasingly prevalent on new cars. There, though the driver is continuously in command of the vehicle – though may not, system depending, have their hands physically in contact with the wheel at all times – the ADAS contributes some degree of control.

It’s typically used on the highway, where systems like Tesla Autopilot, GM Super Cruise, and Mercedes DISTRONIC PLUS aim to take some of the stress out of maintaining pace with traffic and keeping the vehicle centered in the lane. Nonetheless, despite what some owners might believe, such systems are not truly autonomous. That is to say, the car is never capable of operating without human supervision.

Levels 3 through 5, though, do see that take place. In Level 3 – not currently commercially available in the US – vehicles are able to operate independently, without supervision, in select environments. Typically that means on certain pre-mapped stretches of divided highway. Outside of those regions, the car signals to the human driver that they need to resume control.

Level 4 and Level 5, meanwhile, squeeze the human involvement out even further. Still, while multiple companies are testing deployments of “true” autonomous vehicles on public roads, so far there’s no commercially available vehicle that can be bought that doesn’t require driver attention in some way.

Regardless, the National Highway Traffic Safety Administration (NHTSA) now says that it wants to hear about all ADAS or ADS-related crashes, assuming they are on the serious side.

“Vehicles operated using Level 2 ADAS present safety risks to occupants of those vehicles and other roadway users, in part due to the unconventional division of responsibility between the vehicle and its human driver,” the NHTSA points out. “Misuse of an ADAS (including overreliance by a driver) may create a foreseeable risk and potential safety defect.”

“Other potential safety issues with vehicles operating using Level 2 ADAS include the design and performance of sensors, software algorithms, and other technology used to analyze and respond to the vehicle’s environment; technology and strategies to ensure appropriate driver engagement; and the evolution of the system over time through software updates,” the agency adds.

Now, when the new Standing General Order comes into action, companies must report crashes involving a Level 2-5 equipped vehicle within one day of learning about it. That’s assuming there was a hospital-treated injury, a fatality, a vehicle tow-away, an air bag deployment, or a vulnerable road user such as a pedestrian or bicyclist. Updated reports are due 10 days after that.

Each month, meanwhile, companies must report all other crashes involving ADS-equipped vehicles, if they’ve involved injury or property damage. A new incident form has been developed for that purpose.

“These data will help the agency identify potential safety issues and impacts resulting from the operation of advanced technologies on public roads and increase transparency,” the NHTSA explains. “Access to ADS data may show whether there are common patterns in driverless vehicle crashes or systematic problems in operation.”
