Or there are better other ways to tell a FSD car that the road is closed. We could use QR code or something like that which includes info about blockade, where you can drive around it, and how long it will stay blocked. A FSD should be connected enough to call home and give info to the servers, those then update the other FSD cars, et voila tadaa.
Why should it get obscured? Just plug that giant QR code there. You can create QR codes, where you only need to see very little of the square to get all the info in the QR code. I don’t feel like obscuring would be any problem.
Wow, you solved one of the really easy self driving problems (sign recognizion) with a more complicated solution.
Sign recognition and traffic light recognition are available in a lot of cars. Detecting that the dark lump on the road is just a shadow and not slamming the brakes automatically is the hard part.
Or that the white sky is in fact not a white sky but the sideways view of a semi trailer.
(The latter issue is why relying on multiple sensors camera+radar+ultrasound in the case of my car’s emergency brake system and drive assistant is always a lot better - each sensor on its own has its failure modes)
