Is it possible that since you drove back immediately after the update, there was some response learning over the course of the trip? I have had one experience where I loaded 1.5 sets of wheels/tires into the back of my S. total weight was probably around 250lb at about the rear axle centerline. I immediately noticed the difference in steering response and feel. (those of you with towing experience will know what I'm describing)
What was interesting was how autopilot behaved under this condition. At the start of a 50mi drive, autopilot wandered back and forth in the lane. But after about 20 miles, it became much more stable and seemed to steer the appropriate amount. When I unloaded the vehicle and made the return trip, it followed the same process...starting out poorly following the lane with many corrections back and forth, but later recalibrating itself back to its original capabilities.
The nav has sucked since as far back as I can remember. I usually check the map, and compare it to my phone's nav, if it's close enough I'll follow the 17" map. If it's different, I usually follow google maps on my phone.
Tell Tesla about it. "Nav sucks" isn't a message that will help Tesla, no matter how good it feels in the moment.
The story you told in the post with the map image on the other hand, gives Tesla somewhere to start - and if they figure out why you have an issue, maybe they'll unlock a whole class of issues and Nav will get better.
They can't fix it until they know it's broken, and how in particular. I've read that some Tesla folks read TMC, but I think you should send it to Tesla directly.
The road is probably 100 years old, but has only been paved for 50 or so.
I just put that trip in Google Maps and it correctly highlighted the 3 mile route...so it does appear to be an issue with Tesla's routing.
Do what most of us that can't trust Tesla's Navigation system do. Use Apple Maps, Google Maps or Waze on your iPhone. What happened to you happens to me at least once a week. It boggles the mind why Tesla can't figure this out.

Certainly possible. I have a little over 500 miles on it since the update, with the majority being the drive back on the long trip. Only a few miles and limited AP use locally since then. I would love for this to be a 're-calibration' or 're-learning' (individually or fleet) thing. For some reason my instinct doesn't gravitate to that conclusion, but I would love to be wrong.
Thanks,
I was starting to feel like I was doing something wrong. I guess that Tesla's nav system doesn't learn the way Waze seen to.

No but a rework of Nav with added features was supposed to be part of 8.0 per the leaked info we read about several weeks ago. Here's hoping it will be updated in 8.1 and we are not here waiting another year for 9.0 to have it.

Here's a new "feature" that I just discovered in 8.0 that limits AP even further:
On undivided highways where AP limits TACC speed to the speed limit + 5mph, engaging Autosteer now only allows you to set TACC's max speed to 5mph over the limit.
In 7.1, you could set a higher speed (e.g. 50mph in a 25mph zone) and engaging Autosteer limited the car's speed to 30mph, but this didn't change the 50mph max speed. Then once the speed limit was lifted to a higher number, the car would automatically accelerate to the new limit (5mph over, or 50mph, whichever was lower).
This was useful in situations such as temporarily driving through a town with a low speed limit. However if you now engage full AP (TACC + autosteer) while the limit is low (say 25mph), the max speed TACC will get to is 30mph. Pulling the speed stall up won't allow you to go higher than 30.
So after the speed limit changes to a higher number, the car will only go up to 30mph even though the new limit might be much higher, such as 55mph.
I haven't tested the situation where AP is engaged with a higher speed and a lower limit is encountered to see if the max TACC speed automatically lowers to the new limit + 5mph, or stays at the original TACC speed. I would assume (hope) it doesn't change down, but as it is this new "feature" seems like another step in the lawyer-mandated CYA direction..

What if you disengage then rengage after you're in the new 55 mph limit, will it go up?

This was required to solve the issue where the car accelerates wildly if you disengaged autosteer only. One could argue about the holistic solution, but this is necessary given what the rest of the interface is.
And it still doesn't fix that problem. Say I'm in a 50MPH zone behind a car going 30. TACC slows me to 30. I turn the wheel to get into the turning lane, AP disengages, and the speed zooms up as I prepare to turn.
I really appreciated how, in 7.1, I could set the AP speed to, say, 70 and it would change speeds up and down as I drove through speed zones. That no longer works, and I now have to keep manually re-upping the speeds. So, it broke my valid and common use case and didn't fully fix anything, which makes me wonder about who designs these things.
Disengaging AP should set TACC to the current speed, in my opinion.
I think a setting that allows "link auto steer speed restriction to TACC speed restriction"
Basically, you want to have auto steer and tacc linked together as you enter a speed limit zone or rural town.
The system knows it is limiting due to a undivided roadway...it is dynamically adjusting the max speed to 5 over as you go through various speed zones...just need the option to latch tacc to the same speed.
