I have a Y on order. Biggest omission I see is lack of a dumb cruise control mode, when the the vision only ACC throws fits. I drive a lot of 2 Lane roads with semis, shadows as in trees, that seem to be problematic with phantom braking.

That's weird that you can't engage a basic CC, when that is what you want.

The more people who sign up as Beta Testers, the better!

FSD and TACC are always recording in every new Tesla. Tesla made the decision long ago to outfit every car with the same hardware regardless of whether the owner pays for and uses it. The AP functions are active regardless, and Tesla has access to the data from the entire fleet. That is why all Teslas have the same safety features, activated for everybody.

Amazing forward thinking on Tesla's part.

The drive from Moab back to SLC requires either staying at 60 MPH on 80 MPH roads or one Supercharger stop. It was interesting to watch the meter start ticking over 600 miles per hour charge gain and at about half full begin tapering to 400, then 300 and finally to 250. The tapering would have continued, but we had plenty to get home, where the L2 EVSE was putting in 25 miles per hour gain.

Sounds like you were at an old Supercharger. Wait till you experience a new (V3) one.

I wonder if the variations are due to differences in vehicles. I don't have phantom braking in my Tesla Y. Others do. I think the same variations might well exist among FSD users. Just a guess.

Most certainly. @cyaopec has HW2.5 in a Model S I think that probably differs in number and locations of cameras as well as compute power. If radar has been disabled for all, then fewer cameras should result in lesser performance.
Not sure what release will activate Dojo nor how that affects the on board computer. Somewhere I think I read that even HW3 is not up to task for 100% vision and they will need to upgrade all FSD cars again.
I still get occasional phantom braking and as mentioned earlier, will attempt to put some miles on 10.5. My few miles so far seem smoother but still too hesitant taking off from a stop sign but accelerates much faster than before which is better. Before, it wouldn't keep up with the blue hair in front of me leaving a stop light.

First off, RADAR is not a camera.
Second, there are processing efficiencies gained from not having multi-modal inputs. The trade-off net result is just about impossible to guess unless you are Tesla, but they obviously think that as the NN improves the trade-off will too.

I was alluding to a 2016 Model S may have fewer cameras than a Model Y and without the help of radar in both, the one with fewer cameras "should" result in lesser performance.

So far as I know, the RADAR is not disabled in the 2016 Model S ... or in any Tesla so equipped. The change Tesla made was to stop including RADAR in recent cars.

...The Tesla's owner says, "Trust the technology." but there was a vertical sandstone bluff staring us in the face; trust, but verify....

The Tesla owner is a fool, hope that isn't too harsh when applied to your friend / relative but it is a fact. The owners manual says "don't trust the technology, you are in control of the car"...

Maybe the manual has a coffee stain over the word "don't"???

Others have reported the same, but there’s no question my EUV is using the mechanical brakes going down hills. I’ve tested both with and without cruise enabled, both with and without one pedal turned on. Regen maxes out at 10kW on cruise, while it goes much higher without cruise. There’s no other explanation for the difference.

I hope that the battery replacement on the earlier cars doesn't result in this horrible behavior in those cars!

Isn't yours a 2020 or early 2021 with Radar?

It makes sense though, considering humans don't have radar or lidar. At some point it may be possible to achieve at least the same safety standard as human drivers using cameras only.

That said, I tend to think there's safety advantages to be had by employing other sensors that can cut through fog, for example.

Maybe someday our vectors will all be known, considering almost everyone is carrying a GPS (smart phone) on them regardless of if they are walking, biking, or driving. If vectors of most people are known, then most of the serious accidents could be avoided.

Nope, doesn’t seem to be the case. Used cruise control extensively last weekend and I’m almost certain I saw regen exceed 15kW.

I like actually driving a car. I don't find it so challenging that I desire it to be automated.

1. Two words: Optical Illusion.
2. Exactly! Why not use advanced technology? Yes, it adds to the cost.
When you make the 'Only True Hands Free' Driver's Assistance package ($5000?) it uses a Lidar unit.
3. ADS-B for Cars! It's coming. But then,,, The creatures in the woods aren't online. You need radar/lidar.

That is strange behavior.
How are you certain the friction brakes are slowing down the car? Did you point an IR temp reader at the discs?

I came down Pikes Peak in my Volt years ago like the dumb tourist in front of me. I could smell the hot brakes.
We both just used the brake pedal in D, (I assume).
At the Park Ranger safety stop they read your brake temps.
She was told to "park over there and let your brakes cool off".
Mine were 69° on a 65° day. I asked him to measure front and rear.

My certainty comes from the car speed being controlled going downhill, with the lack of regen higher than 10 kW. I could also feel the speed being controlled, and it was a bit rough, as if it was applying and releasing the brakes. Going down the same hill, but using regen to control the speed (one pedal more or using the brake pedal) I saw significantly higher levels of regen, and I could hold the speed smoothly. Really noticeable from the driver’s seat

Dan, you see and feel what you saw and felt, but in four-and-a-half-years of Bolt ownership in hilly/mountainous country, ours just doesn't behave that way.

When we first got ours and were charged to 100%, starting out down a steep hill, there was no regen; since that experience, we've always used Hilltop Reserve and whether on cruise control or manually in L or L+paddle, maintaining the cruising speed feels the same and I've never felt the "bit rough" you describe.

All I can figure is they changed something for 2022. Before my Bolt i drove a PHEV, and I understand regen limitations with a full battery. That isn’t the case for me, as I don’t charge over 90%, and my testing is coming after some additional driving. It’s certainly strange, but I’m certain of my conclusion.
