Dark and Rainy Night
A Tesla running the latest version (FSD 10.2) of its self-driving software. Has to work even when it is dark and rainy. An example why a camera-only approach is useful, because if the car is driven blind using radar (eg. through thick fog), the human driver can't verify the self-driving.
An AutoX robotaxi navigating through a busy, narrow street. Notice how hesitant the vehicle is; because essentially it is likely programmed to observe 'if hooman steps in front of car, apply brakes'. This is where machine learning is indispensable: have skilled drivers assertively inch their way through the crowd and then get the software to learn from the drivers.
