Yes, there some places and times where a Tesla might be worth the money; maybe

Some family members have a place in Moab, UT and we love to send time there with them hiking and visiting the six state and four national parks. Seeing is not believing; just beyond human comprehensionl

The roads through the parks are always crowded, 30 - 45 MPH speed limits, curves, hills and spectacular scenery on both sides and sometimes straight up and straight down.

They have a Tesla with autopilot and follow cruise; these two features our Bolt lacks makes the day in the park in a Tesla a walk in the park. Thanksgiving weekend is crowded and there was a twenty-minute-stop-and-go line just to get into the park; follow cruise made that cake. Then, set the autopilot at 45 MPH and the Tesla does the rest. If the car in front doesn't hold a steady speed, the autopilot can be set to maintain 1 - 5 car lengths behind the car in front and follow the road. A gentle hand resting on the bottom of the steering wheel is all that is necessary and the driver can enjoy the scenery as much as the passengers. Tesla knows when the speed limits change and will slow and go as necessary.

Having said how much I love autopilot in that situation, there are times it gets it wrong and will scare the shite out of everyone in the car. A cyclist on the shoulder will cause autopilot to panic, slowing rapidly, beeping warnings and switching off. Coming down the mountain toward the park entrance, there are a series of 15 - 25 MPH 180-degree switchbacks. The autopilot had been slowing for most of these, but the last one it ran straight into it at 45 MPH, not noticeably slowing. The Tesla's owner says, "Trust the technology." but there was a vertical sandstone bluff staring us in the face; trust, but verify.

Bottom line, the Tesla autopilot is almost as smooth as a really good driver; but it's not yet anywhere near autonomous, but in the situations for which it is suited, it's magic.

I find it odd that AP can't take turns at "normal" speed or anticipate when to slow down. I would think that would be something trivial for a computer to calculate. Then again, there are no pilotless fighter jets. So perhaps high speed maneuvers are more difficult than a layperson realizes.
Well, actually it can. Takes turns at "normal" speeds at curves in the road. Just for giggles I turn on AP in our model Y when on regular streets, side streets, twisty streets; works really well. And, yes, I'm paying attention to what's going on around me.

Now, FSD is another matter. That has a way to go yet, IMHO.

With HW 2.5 it goes fast into turns and then brakes coming out, which is the opposite of how normal people drive. There's no way a Tesla engineer could ride in my car and say that it feels "normal" when turning. So it must be a sensor/computer issue because if it could be "smoothed out" with software it would have been done. I'm obviously talking about higher speed, twisty roads, which you should not use AP on. It's fine on the freeway.
Are you on 10.4 or 10.5. I haven’t had much opportunity to run it through its paces but from what I’ve read, it’s a much bigger improvement than previous .X releases.
And for those interested in getting firsthand feedback, I’d recommend the TMC forum on FSD. With ~13,000 beta users logging millions of miles/month, there’s plenty of feedback. Of course you have to sift through the noise and filter out the negative Nancy’s and Tesla worshippers but the median is filled with tons of anecdotal data, so much so that it can be looked on as just data. Similar to the wide range of opinions on this forum related to EA chargers. In the past, some have claimed the experience, strategy, locations, density, business plan is superior to Tesla’s superchargers while others claim a 50% success rate a major win. Truth lies somewhere in the middle.
Sorry. I don't have FSD. I'm only talking about using Auto Pilot on back roads in my Model 3, not Model S. It's not a big deal. I'm just surprised that there's a limit to how it can navigate corners. It's gotten a lot better over the years. It might just be that some design decisions are ones that I would differ with. There may very well be a good reason why it brakes at a turn's apex. It's just that I would wager that most people brake before entering a turn.
