Indicator half press vs full press

[rpiotro]

My best friend has a cousin in Germany. He only does a single blink when changing lanes. My friend isn't sure why. Hasn't asked.

If I had my druthers with auto-cancel turned on a half press would activate the auto-cancel function and a long press would keep the blinker on until the steering wheel is turned or I turn it off.

Yes, half press should give 3 blinks of your indicators. If yours is not doing that you are either pressing it too hard and accidentally doing a full press, or you need to have service look at it.

The reason why the half press is not turning off after 3 blinks is because they have the auto blinker cancel setting set to ON.

I believe there’s another thread (here or elsewhere) where I was schooled on this.

As LORK said, the auto-cancel setting seems to have undermined the standard soft/hard turn signal logic as described in the OM. Almost as if two parts of the Tesla team aren’t talking with each other even on basic functionality; but that would never happen at Tesla.

i agree - i don't remember last time my Y or 3 blinked 3 times.
Its ALWAYS waiting for me to "complete maneuver" - to a point i often intentionally move the steering wheel to force it off

With auto cancel turned on, there is zero difference between half press and full press.

Not entirely true. You have to do a full press to force a lane change when FSD beta is active. I suspect this is also true for Auto Lane Change when standard Autosteer is active (with Enhanced Autopilot or regular FSD) but I haven't tried it. If you only half press in this circumstance, the blinker will be activated while the stalk is held down, but an auto lane change won't be initiated.

Interesting, I paid attention today while driving. Mine absolutely still blinks 3 times on a half press and am on a recent firmware (2023.20.4.1). But I also appear to not even have the auto turn signal feature in my controls, much less the auto turn signal cancel setting. Probably because I am HW 2.5 and also don't even have AP/TACC.

Interesting. I just tried turning off auto turn signals and hey presto! It now does three blinks on a light touch. But now I would guess that now the turn signal won't turn off automatically. Have to wait for a test drive.

Nope auto cancel works perfectly as well. I don't seen the point in turning on "auto turn signals" in controls. It effectively stops the light touch three flash turn signal from working if you turn it on?

The default "dumb" behavior is signal cancels when steering wheel returns to center.

With Auto Cancel, they also cancel once you finish changing lanes (even if there isn't as much steering movement to trigger the centering cancel).

Has this changed in a recent update? A half press only stays on for a few seconds now for me. The auto indicator is still turned on.
