Self-driving systems are moving beyond rigid rules into learned intelligence. Alex Kendall explores how Physical AI enables vehicles to perceive, reason, and act in the messy reality of our streets, no maps, no manuals, just the ability to handle whatever the world throws at them. The implications stretch well beyond the car. The same principles are beginning to reshape robotics, logistics, and any industry where AI needs to operate reliably in the physical world. What can the journey to autonomous driving teach us about building AI that works beyond the lab?
