Long before Tesla promised autonomous driving, mid-century logistics hubs had 'trackless trains' that followed simple optical lines painted on warehouse floors. These automated tuggers pulled heavily loaded carts through sprawling factories without a human driver, relying on primitive but bulletproof light sensors. It was the absolute peak of 1950s automation, gracefully dragging tons of cargo while completely ignoring the union guys staring at it in existential dread.
