Are most those 40k miles in the last year or so?

> I just wouldn't use cruise control in heavy traffic

Assuming you’re staying in one lane for a bit, AP actually shines in heavy traffic (especially stop and go).

> I'll be driving on I-80 through Nevada or Utah and every ~10 minutes the car will slam on its brakes.

Two points:

1. The update I spoke of was in spring 2022. AP improved a lot with that update for me. Shadows stopped triggering phantom braking. Trucks driving it adjacent opposite lanes on highways stopped triggering phantom braking. It took away the most egregious errors, imho. So if you’re talking about trips mostly before the spring 2022 update, i can believe it. If it’s after spring 2022, then…

2. Nevada can have lots of reflection mirages due to desert heat. Not sure about Utah, but it wouldn’t surprise me if that was the cause there as well (if it happened have the 2022 update).

I have my criticisms of teslas as cars and as a company, but autopilot is not one of them.

> I wish there was a way to make my cruise control "dumb"/non-adaptive just to stop the random abrupt braking in the middle of nowhere.

Agreed. This is one feature I hope that they are forced to make.

My biggest use case of it would be when it’s raining. AP still forces auto wipers when it’s raining, and it often runs too long (when there is no more rain) and/or too fast.

Of course, since I live in CA, rain is rarely an issue.

The absence of regular cruise control in my Model S Plaid is incredibly frustrating on road trips, particularly since Traffic-Aware Cruise Control (TACC) maxes out at 90 MPH - which is the speed limit on at least one U.S. road. Moreover, if the camera can’t see to its satisfaction, TACC’s maximum speed is even lower.

Camera can’t see ≠ I can’t see perfectly well. It’s dangerous to not have cruise control available at speeds that keep you with the flow of traffic.

Also, autopilot having a maximum speed of 85 MPH makes it essentially unusable on many interstates, where the speed limit is 80 MPH and the flow of traffic is 90 MPH.

So dumb.
