This time I was cruising down the freeway at 70mph when a car turned on his signal to merge into my lane. He was on the on ramp. All of a sudden my Y did some extreme braking thinking we were going collide. It was not even close for a human but the computer freaked out. I decelerated so quickly I almost got hit from behind but I was ready (because of phantom braking in the past, I now keep my foot on the throttle ready to go) and jammed my foot down on the throttle and over rode the system. Not as scary as a 737 MAX fighting the pilot but close enough for me. I am seriously regretting buying the FSD option. These cars are a long way from a true self drive experience. In fact I will say on record right now until all cars on the road have FSD, it will never work completely. Too many human variables in regular cars that the computer cannot understand .
