Did you see this first hand or was it or just reading about it in the media??
And really, "FSD" is too specific, even the lane keeping autopilot the car comes with by default has the same problems. I love my model 3 but let's call the spade a spade: advertising the car as having "full self driving" at this point in time is nothing short of fraudulent.
I think the main issue is that Tesla is seen to be 'fire fighting', rather than working according to a predetermined plan.
