Humans don't just use vision when driving a car. Our eyes also aren't fixed in our heads. They can gimbal independently of our heads. Our torsos also give our heads more degrees of freedom than just our necks. Human senses are actually fairly good. The main issue with vision-only FSD is that visual artifacts don't convey high degrees of certainty about the solid nature of things. If the AI doesn't recognize an object as being an object it can't add it to the list of things to worry about. If it's augmented with LIDAR and radar it doesn't need to recognize an airplane to know there's a solid object in its path. It's dumb edge cases that cause problems. Vision-only FSD leaves a lot of edge cases on the table with the hope that AI magic will save the day.
