I walked by the East Madison St – 14th Avenue intersection this afternoon where my Tesla’s Full Self-Driving (Supervised) function made a boo-boo yesterday (just to check it out again).
The green light shapes are ‘Straight Ahead’ arrows, and there is a NO TURNS sign on the beam as well.
Even so, as the car approached the intersection from Madison Street, the FSD turned on the turn signal, and turned left onto 14th Avenue.
There was no oncoming traffic, and I should have tapped the brake or held the steering wheel (to override the FSD controls) to keep going straight.
