The SAE press release also notes that the update does not include driver warning and momentary driver-intervention systems in the classification of these levels. For some, this may relate to the recent Tesla crash in Texas that prompted policymakers to call for driver monitoring even in the lower SAE levels.
Actually, J3016 clarifies that stand-alone crash avoidance features equipped on conventional vehicles without ADS, such as automatic emergency braking, electronic stability control, and blind spot intervention, are subsumed by an ADS whenever one is engaged. Tesla’s Autopilot, however, is not an ADS, but a Level 2 driver support feature. And the preliminary NTSB investigation apparently proved that Autopilot was not engaged during the crash in question, although adaptive cruise control was.
Regarding driver monitoring systems, Tesla has been using a steering wheel-based system that looks for hand contact and wheel torque as an indication of driver engagement in the driving task. This DMS, however, proved easy to defeat using a counterweight hung on the steering wheel, and otherwise allowed a driver to rely on Autopilot’s ability to maintain lane position – and to even leave the driver’s seat, as some users did. However, in late May, Tesla announced that it will start using an already-equipped interior driver-facing camera on the Model 3 and Model Y to monitor driver compliance with Autopilot’s requirement that the driver remain seated in the driver’s seat, and that they maintain attention to the roadway while Autopilot is engaged.
