Wide Turns with basic AP

[Dr_G]

For context, Tesla enthusiast here! 2023 M3, 12k miles.

I use AP a lot and am generally very happy with Cruise and Autosteer in basic AP (do not own EAP or FSD).

HOWEVER, I've been noticing that even in moderate curves, autosteer takes a long time to adjust and usually does not stay centered. Turns are wide and touch the markers. Don't know if it's any better with cars alongside. Very surprised that such a basic function could be so flawed.

So my question is this: For a basic turning function without anything extraneous, would EAP or FSD use the same software/AI and exhibit the same flaw?

Related, how could this apply to my vehicle only, since that function must be stable software??

Would love to know what I'm missing.

Thanks !

EAP wouldn’t be any different, FSD Beta might be. I haven’t had your issue: how fast are you going and what’s the speed limit?

All nominal: Traveling at maybe 45 with 40 speed limit.

FSD beta stays locked in the center of the lane on moderate curves on the highway. It runs new code vs AP & EAP, which are using a codebase that is largely unchanged for several years now.

Source: I own a model 3 with FSD and model Y with base AP.

This is a constant problem on non-divided roads. Also horribly bad is TACC panicing when an oncoming car appears around a bend. All cars are nicely in their lanes, but a hard slowdown ensues. Really quite poor.
