Stop sign problem with TACC - stops before traffic is visible

[n.one.one]

While I see many good things about stopping at stop signs under TACC and Autosteer I've experienced one very serious problem and it will be interesting to see how this gets solved.

I regularly approach a stop sign at a T intersection and the cars coming from the left and right don't have a stop sign. My vehicle does what it's supposed to do with TACC and stops exactly at the line. The problem is my vision is blocked at that point. If I pull the Autopilot stalk or briefly press the accelerator pedal to proceed it will accelerate into potential traffic from the left or right. My only safe choice is to disengage TACC and then creep forward to watch for a safe time to proceed.

I haven't found any workaround. Any thoughts on how this might get solved?

You're going to have to disengage anyway to make a turn right? What's the problem?

Good point. So let's eliminate the T intersection and assume I'm going straight. The problem still exists.

Ok.

Edge case that will be solved eventually through further NN training. Remember this is a brand new feature, it likely can only handle simple straightforward cases right now. It will get better over time.

It should do what you do...stop at the stop sign, and if it can't confirm the cross traffic is clear, it will inch forward as far safely as it can, then proceed through the intersection (or turn). This hasn't happened yet, but def not something that can't be solved.

I've had a different kind of stop sign problem. For me, there are certain stop signs in my neighborhood where the car stops WAY too early. Like 1 1/2 car lengths before the line. It must be using map data because it is always the same ones.

Also, it has a tendency to get all herky jerky sometimes as it comes to a stop. No idea why.

The odd thing is, it works great for traffic lights. No problems at all.
The other odd think is that it didn't have the stop sign issue until the 2020.12.11.1 release. The previous one worked much better.

Not too concerned about it, I'm sure they will iron it out. But for right now, I'm not very comfortable using the stop sign part of the feature so I just drive the old fashioned way on back roads and turn on FSD on larger roads with lights and / or hiways.
