I have "learned" to use the old AP and NOA to help with my long drives to and from LA/SF.
1) always double tap brake to disengage.
2) always disengage when feeling unsafe. Like passing big trucks, congested high speed traffic, etc
3) try to stay away of merge lanes on interchanges.
4) always do your own freeway interchanges and exits. Try to get to the exit lanes early and wait in line.a
5) disable auto lane change.
6) watch for clear lanes to initiate lane change manually by signalling.
7) never use AP on two lanes (one each direction) highways with sharp turns.
8) never follow too closely as you may not know whether the car in front will stop suddenly if it encountered hazards which you cannot see. Especially on left lane left curve and right lane right curve.
9) disengage on bad roads with potholes.
I have yet to test 11.4.4 on long trips.
It seems as you have gotten used to behaviors that were needed during older versions. What's running today handles most of these situations extremely well.
1) Not sure why you double tap, a single tap is all that's needed
2) This is actually some of the places where the car does an awesome job. Passing trucks, the car will move over a little if the next lane is clear. If a truck swerves into your lane, the car will swerve (if the adjacent lane is clear) and/or slow down as appropriate.
3) Most of the merge has been fixed
4) Car does a great job
5) There is one thing that I trust the car to do even better than I can, that's lane change. It seems to have this down to just about perfection!
6) Same as 5, turn the signal on and just sit back and wait for lane to clear and car move over.
7) Someone recently posted a YouTube with FSD on some small mountain roads, often without lines, and the car successfully navigating them. It does a MUCH better job than 3 years ago.
8) I'd have to say that the car is going to beat you every time. The car is CONTINUOUSLY monitoring the distance between you and the car in front and it'll hit the brake many, many milliseconds before you do. I wish it would give more gap though.
9) I just dodge when I need to. Once you learn how to overcome FSD with the steering wheel, it's not that hard to smoothly disengage without jolting the entire car.
