NHTSA has denied a petition asking it to open a defect investigation into the hidden manual door releases on the Tesla Model 3. But in the same decision, the agency agreed to start writing new door-safety rules for the entire auto industry.

The denial, published today, covers 179,031 model year 2022 Model 3 vehicles. NHTSA said it found exactly one complaint matching the petition’s allegation — and it came from the same owner who filed it.

Tesla reported 207 crashes involving its driver-assist systems in a single month — the most it has ever logged. The figure comes from Tesla’s own crash reports to the National Highway Traffic Safety Administration (NHTSA).

The record month lands as Tesla pushes Full Self-Driving harder than ever, and as the company continues to redact nearly every detail of what actually happened in these crashes.

NHTSA is now demanding a Tesla internal document titled “Radar Saves Us” as part of its investigation into “Full Self-Driving” crashes in low-visibility conditions.

The request is buried in a new 24-part information demand sent to Tesla on July 2, and it points the probe straight at the decision that started all of this: Tesla removing radar from its cars.

Tesla has filed four new “Robotaxi” crash reports with NHTSA, and the most revealing one involves a Tesla remote operator driving the vehicle into a tree stump in Houston.

It’s the third crash Tesla has now reported involving a human operating the car remotely caused the collision — and the first one Tesla has formally coded as remote operation in its filing.
