Politicians have followed suit and expressed great excitement for the future of transportation systems. SAE International’s experts classify vehicle autonomy using a six-level scale (0–5). On level zero, the driver does everything while the car does nothing autonomously. From levels two to four, control gradually shifts from the driver to the car while...
