Navigate on Autopilot has mostly worked fine for us. However, the is one specific off-ramp that it struggles with. As expected, it engages the turn signal and turns onto the off-ramp, then just as it gets past the dividing line marker between the freeway and off-ramp, it suddenly jerks back toward the freeway, then immediately jerks back into the off-ramp and continues smoothly. The puzzling thing is that this particular off-ramp is extremely benign. There are no characteristics that appear to be a challenge in any way.
We have taken this off-ramp daily for the past three weeks and experienced the same behavior every time but two. On those two occasions the barely twitched. They happened just after the car updated from 2019.5.4 to 2019.5.15, so we jumped to the assumption that Tesla had addressed the issue. Subsequent, multiple, "jerking" experiences proved that conclusion pre-mature.
All of this is well within the expectations of Beta features, so "hands-on-wheel" and "brain totally focused". Probably even more important than if AP were turned off, because the Tesla AP driver not only has to be prepared for other drivers' behavior, but also for their own car's behavior!
