And bullshit on you not being able to see the lights. They're specifically designed so that's not an issue for colour blind people

Some lights are, but not all of them are. I often say I go when the light turns blue. However not all lights have that blue tint and so I often cannot tell the difference between a white light and a green light by color. (but white is not used in a stoplight and I can see red/yellow just fine) Where I live all stoplights have green on the bottom so that is always a cheat I use, but that only works if I can see the relative position - in an otherwise dark situation I only see a light in front of me and not the rest of the structure and so I cannot tell. I have driven where stoplights are not green on bottom and I can never remember if green is left/right.

Even when the try though, not all colorblind is the same. There may not be a mitigation that will work from two different people with different aspects of colorblind.

Human vision is very, very, very good. If you think a camera installed to a car is even close to human eyesight, then you are extremely mistaken.

Why are you trying to limit cars to just vision? That is all I have as a human. However robots have radar, lidar, radio, and other options, there is no reasons they can't use them and get information eyes cannot. Every option has limits.
