NHTSA Lets Tesla Off The Hook |
TOKYO — The National Highway Traffic and Safety Administration (NHTSA) concluded a months-long investigation of a fatal crash in Florida last May, and reported Thursday that the agency found no defects in Tesla’s Automatic Emergency Braking (AEB) and Autopilot systems.
Definitely, Tesla is exonerated.
Did NHTSA let Tesla off the hook too easily? Absolutely.
What lessons or guidance, if any, did NHTSA’s findings offer to the rest of the
automotive industry? Very little.
It’s important to point out that nobody is saying that NHTSA didn’t do a
thorough investigation. It did. NHTSA’s report, however, exposed limitations in
the scope of their probe. The investigation revealed the difficulties regulators
face in dealing with highly software-dependent automated driving systems.
Further, problematic was the tardiness of the investigation. Tesla was able to
move much faster than the regulator to fix some of the problems (if not all of
them) via over the air (OTA) software updates. That’s a good thing, but it
rendered the NHTSA probe less than remarkable.
After reading the report, Mike Demler, senior analyst at The Linley Group,
complained that NHTSA “largely just matched up the parameters of the incident
with the information Tesla provides in owner’s manuals, along with cockpit
warnings.”
NHTSA calls the report issued Thursday “ODI
(Office of Defects Investigation) Resume.” A defect is an imperfection, or a
weakness, noted Demler. But in his opinion, he sees little evidence that
government agency actually focused on the weaknesses within Tesla’s Model S at
the time of the accident.

ODI (the Office of Defects Investigation)’s analysis of Tesla’s AEB system finds that 1) the system is designed to avoid or mitigate rear-end collisions; 2) the system’s capabilities are in-line with industry state of the art for AEB performance through MY 2016; and 3) braking for crossing path collisions, such as that present in the Florida fatal crash, are outside the expected performance capabilities of the system.
But hang on. Was that fairly important ODI finding, that “braking for crossing path collisions… are outside the expected performance capabilities of the system,” well understood by Tesla drivers?
