So it's marketed with a nod and wink, as if the supervision requirement is just a peel away disclaimer to satisfy old and stuffy laws that are out of step with the latest technology. When in reality it really does need active supervision.
But the nature of the technology is this approach invites the driver to distraction, because what's the use in "full self driving" if one needs to have their hands on the wheel and feet near the pedals ready to take control at a moments notice? Worsening this problem is that the Teslas have shown themselves to drive erratically at unexpected times such as phantom braking or misidentifying natural phenomena for traffic lights.
One day people will look back on letting FSD exist in the market and roll their eyes in disbelief of the recklessness.
