Yes FSDb. Just because the car passes a thousand speed limit signs and the car changes the speed limit in the car every time does NOT mean it "READ" the sign. That data is not good enough when it is also known that the car uses map data because now you have to be able to separate those two conditions.
Yeah, and when were those tests done? As far as I remember that was as soon as Tesla applied visual sign reading to the MODEL S using the Mobileeye and AP1 hardware. Show me a current test, something in the last 3 years on a model 3.
Your theory can be thrown into chaos by passing just one sign and the car doesn't change the speed limit accordingly. It doesn't mean that there wasn't some other reason, but now you have to figure that out.
My data shows that I have two different physical signs that the car does not react to in any way that the user can see. It doesn't change the round speed limit icon on the screen, it does not slow the car down when in AP(FSDb), AND it doesn't visualize the sign AT ALL on the display. So what is your theory on that?
The ONLY way to really attempt to test this is to get a stretch of public road and toss a speed limit sign in the ground that is say 5mph less than the road speed limit and see if the car changes the speed. I say that a Model 3 will NOT visualize that sign and will not react and apply that speed limit. I would be ecstatic to see someone carry out this test and prove/disprove me. Yes people did this in the past, but it only applied to the MODEL S on AP1.
