What the regulator is examining
On September 4, the US National Highway Traffic Safety Administration (NHTSA) announced an investigation into how Tesla applied existing federal standards when self-certifying Cybercab. The vehicle’s design has no steering wheel, pedals or conventional exterior mirrors. [1 · NHTSA] [2 · Reuters]
Reuters reports that Tesla did not request a separate exemption; the investigation covers up to 1,000 vehicles. The opening of the procedure does not mean the regulator has already found noncompliance. [2 · Reuters]
Why this matters for autonomous transport
Cybercab tests the limits of an approach in which the manufacturer itself confirms that a design complies with rules written for conventional vehicles. The further a product departs from the familiar form, the more important it becomes to show the regulator decision logs, software versions and a reproducible incident-review procedure in advance.

Expert commentary
The next signals will be NHTSA’s requests to Tesla, any requirements for design changes and a determination of which specific standards apply. Until the investigation is complete, it is premature to speak either of full compliance or of a proven violation. [1 · NHTSA] [2 · Reuters]
