Autopilot 1 and one lane marking - why hugging the curb?

[JPUConn]

first - I get it's a driver assist and I love having autopilot 1 more than not having it.

When driving on a backroad with a double yellow line in the middle and nothing to the right except for curbs the car hugs dangerously close to the curb. When an intersection appears the car goes a further away from the recognized double yellow and closer to the upcoming curb.

I'm not a deep learning AI programmer but in my simple if then decision tree mentality i would think that if the car had a known line to follow (double yellow) that it clearly recognizes on the display then why wouldn't the software be programmed to stay say within 2' of the known line?

Moreover the car has the lane width from measuring it before the intersection, looking ahead after it, and from the aggregated map by other vehicles previously driving on this road. Or does it?

It seems like it's programmed to constantly try to find center but the right line is unknown or unreliable. In this situation then program should stop trying to seek out center and instead focus on a set safe distance from the known left line.
