Exactly. Self steering sailboats existed before self driving tractors, but again... keeping a sailboat on a specific bearing is far easier than turning a tractor with any number of attachments towing behind it. Nobody came along and said what Deere did with tractors wasn't original because sailboats could auto steer. What about autopilot on airplanes? The comparisons are endless. It's an interesting article on its own, but any claim to inventing self driving cars on the farm is rather shortsighted... every invention borrows from the past and contributes to the future. The same is true for art, literature, industrial design, cooking, medicine, and almost any other creation. Lets not discount the invention of the self driving tractor, but lets also not discount the leaps that have been made since then in AI and computer learning for understanding road markers, traffic behavior, traffic signals, routing, crash avoidance, parking assistance, etc.
