Exceedingly unlikely unless the lane demarcation is extremely bad. Lane-holding tech is really standard and reliable now (and even if you don't think AP is great, it's not stupider than what ships in mass-market cars).

>>unlikely unless the lane demarcation is extremely bad Which is the case.....a lot of the time actually? At least here in UK the lane marking is frequenly so bad that my Volvo Pilot Assist disengages because it can't see the lanes anymore - and I'm like yeah, duh, I can't see them either.

  The lane demarcation on the freeway south from San Francisco is so bad that it frequently confuses me, and I've been driving on it for 20 years.

    Which one? I always found both the 101 and 280 pretty clear!

      Most recently, northbound 101 under the 380 overpass. But, also just before the 92, and through Redwood city.

Agreed, though I'll add that on the very rare occasion that my Model 3 does lose the lane lines a bit, it tends to very quickly jerk back into the lane once it picks up the lines again. "it drifted slowly to the left, into my lane, before slowly going back into its own lane" does not sound like plausible autopilot behavior based on my experience; even if it was on autopilot and accidentally left the lane, it wouldn't slowly go back to it's lane, it would sharply correct itself as soon as it found out what happened.

  Exactly... and turning on a signal completely turns off autosteer if in base autopilot. Not sure if it could be coerced into automatically coming back on if the car had FSD and the signal was turned back off, though?

    With EAP or FSD, turning on the signal will trigger a lane change

I have lane assist in my 2019 Subaru Outback, and it works well maybe 60% of the time. Most definitely not something I would call “extremely reliable”.

Well, there is one thing that's stupider. There's no cruise control. It's AP or nothing. If I just want the car to do nothing but hold the current speed, like my 1986 Chevrolet Camaro did, it doesn't have that feature. If the cameras don't work for some reason such as a heavy rainstorm, there's no "dumb mode" cruise control as a backup. I find that annoying.

  If you pull down once on the stalk, it should activate cruise control, right? It's pulling down twice that activates autosteer.

    That still does TACC. He wants cruise control without TACC. That is not possible in any modern Tesla, AFAIK. I believe the most recent to offer it was the Model 3 SR, which is no longer available. The SR+ and the Y SR both included AP with mandatory TACC. Its weird, as other cars at least offer an option to disable TACC.

  I wouldn't be using cruise control during a heavy rainstorm. Standing water and hydroplaning plus cruise control = not a fun time.
  - bpodgursky 5y ago
    Yeah this sounds crazy unsafe. Cruise control is for long boring drives down straight highways in high visibility.
