Serious question because I don't know, but what are these other fully autonomous tractors that have been around for years? Deere's system isn't just GPS guidance where it blindly follows some preplanned route, it uses 12 different cameras to see it's environment and can actively avoid obstacles. It can (according to Deere) find its way to a field on its own, plow and plant without human interaction, and can be controlled by a smartphone, all with no driver in the cab whatsoever. You could theoretically launch this while the tractor is still sitting in the barn, then go spend the morning doing some fishing or playing golf or whatever, and when you get back home the field is plowed or planted and the tractor is back in the barn. That's the pitch anyway.
