This principle is glaringly obvious in retrospect, and seeing it put so succinctly actually changed my mind. I previously thought Tesla's approach was an achievable long shot, but I'm now convinced it's fundamentally wrong.

The safety-driver model pursued by Waymo and every other autonomy startup is the only responsible way to train an autonomy network because the drivers are specifically trained to look out for edge cases, versus consumers who will easily be lulled into complacency once the system looks superficially like it's running at level-5 competency.
