You said "AP in it’s current state cannot leave its lane". The current state of AP can. That argument goes flying out the window.Are you kidding? You are referencing to the FSD beta that is not available to the general public. The car in question did not have that version installed.
Now you're changing the argument to "AP version at the time of when the video was recorded" which is "not current" since it's an old version.
Regardless, AP with Nav on AP turned on actually self switches the lane for the driver without the user to intervene. This has been live since 2019, way before that clip was recorded. https://www.tesla.com/blog/introducing-more-seamless-navigate-autopilot
Example (@ 3m25s):
Either way, you're completely wrong. That car did have a version installed that can move off the lane and it's dangerous to the public for you to lie in order to put irrational fear into technology that could a million lives every year.
Nothing of what I say is going to change your mind (maybe you're a $TSLA short or work for legacy auto), which means this discussion is pretty much dead, so I'm going to end it here. See ya.
