@flatbed a camera at 1/2000s exposure is very unlikely to capture these signs correctly. Read the very interesting paper @cafz quoted above for all the details why. I have to admit I am (and have been) baffled by how Tesla might overcome this significant and safety relevant issue, especially considering their cameras are not HDR imaging types, but have a low light enhanced pixel design where color information is traded against dynamic range, which is why the dash footage has such poor colour rendition.
