Instead of Tesla trying FSD with vision only, they should try with more sensors and charge more for the extra hardware. They cannot beat laws of physics by just using vision.
"That looks like a firetruck" says the object identication net, "but after reasoning about it, it is actually just a mural on the side of a building"
And nobody knows how to build such a thing yet so it might be a long time.
that being said as far as I know the cameras they’re using aren’t good enough
LIDAR won't read the posted speed limit, it will only see the shape of the post. But it won't be blinded by reflections, it will never confuse the side of a truck with the sky, it won't miss an object or hole on the road due to poor contrast, etc. It's becoming very affordable, too.
For example, your brain has way better depth info than just parallax in most cases, as it gets info about what is required to keep a distant object in focus and aligned in both eyes. These two values will not ever available to fixed cameras and yet provide direct measurements of distance for your brain.
