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.
FSD doesn't "work fine" driving directly into the sun. There are loads of YT videos that demonstrate this.
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.
Nobody cares that you think v14.7.22b runs well on HW3.1. Literally nobody.
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.
