I would not rule out driverless technology. There will need to be lots of testing and of course it won't work everywhere or in all conditions, extremely wet, marginally passable conditions come to mind, but think of the money manufacturers can make. Instead of putting money into actual iron and parts to create a mobile "office" for us, they can instead get people to pay big dollars for technology which, once developed, can be reproduced extremely cheap ; ie - large profit margin. And we will pay. Just look at what people pay now for GPS. Who would have believed 20 years ago that we would be paying 10 to 15? thousand dollars to have our tractors drive themselves when we could really just do the steering ourselves for free. I know there is the efficiency and the not feeling stressed at the end of the day factor with GPS but wouldn't that apply to driverless technology even more so? If you would have told me 20 years ago that someday a robot would be milking my cows I would have laughed too, but it happened. Things change so much that it is hard to even imagine what will and what won't come true in the future.
