> they definitely already have this for tractors / farming

As in, a significant % of tractors are without human drivers, or as in, a significant % of tractors with human drivers have GPS-based assistance?

I live in a rural area and see several dozens of tractors every day, and FWIW, I've never seen a tractor without a human driver. Yet.

As in the technology is available to make many 'off the shelf' tractors self-driving. I have no info on actual uptake just that there are components available to make 'normal' driving in to self-driving using third party modules
