Is anyone else seeing the Auto Lane Change Unavailable error message when attempting to change lanes to the left using standard autopilot(not NOA) on 20.2.1? For me it seems it will only work successfully if I am on a divided highway, there is a raised median, all traffic is flowing in the same direction such as a one way bridge. All other attempts to change to left has the blinker flashing for a bit and then the error message. Auto lane change to the right is working normally as it always has since the feature was released.
I have verified via Tesla diagnostics that this is not a hardware or lane marking issue as well as submitted a bunch of specific and detailed information that they have reviewed. I am just wondering if this is effecting everyone on 20.2.1 or if it’s more of a unique case. I am surprised to have not seen anything about it on the forum yet. I use AP all the time so not being able to change lanes to the left without disconnecting was immediately apparent and a bit of a bummer. Although, I’m sure it will be addressed quickly in a bug fix update.
For all the regular “autopilot is only to be used on divided highways” posters who are chomping at the bit to lay down their usual lectures can save their figurative breath. I respectfully disagree and am looking for some input from the rest of us.
