I always see this argument but from experience I don't buy it. FSD and its cameras work fine driving with the sun directly in front of the car. When driving manually I need the visor so far down I can only see the bottom of the car in front of me.
The cameras on Teslas only really lose visibility when dirty. Especially in winter when there's salt everywhere. Only the very latest models (2025+?) have decent self-cleaning for the cameras that get very dirty.
For which car? The older the car (hardware) version the worse it is. I've never had any front camera blinding issues with a 2022 car (HW3).
The thing to remember about cameras is what you see in an image/display is not what the camera sees. Processing the image reduces the dynamic range but FSD could work off of the raw sensor data.
It doesn't run well on HW3 at all. HW4 has significantly better FSD when running comparable versions (v14). The software has little to do with the front camera getting blinded though.
"works fine" as in can follow a wide asphalt roads' white lines. That is absolutely trivial thing, Lego mind storms could follow a line just fine with a black/white sensor.
This vision clearly doesn't scale to more complex scenarios.
