I'm sure Tesla's engineers are qualified and it is certainly easy to second-guess them, but it is beyond me why they would even consider a BW camera in a context where warning colors (red signs, red cones, black and yellow stripes, etc.) are an essential element of the domain.

- stetrain 8y agoThe cameras in Tesla's non-Mobileye cars are grey grey red. Supposedly this gives you higher detail resolution while still being able to differentiate important sign colors. https://twitter.com/elonmusk/status/798886670468644865 https://twitter.com/elonmusk/status/798886670468644865
- stefan_ 8y agoYou can have different cameras for sign recognition if you can't deal without color. But BW cameras have huge benefits from sensitivity in the optics all the way to processing power in the backend without much downside.
- Piskvorrr 8y agoOh, you can deal without colors, but you're intentionally depriving yourself of data, as you now have Safety Gray, Danger Gray, Warning Gray and Traffic Gray. Not to worry, those colors probably didn't mean anything important anyway.
