This, I expect. It's what auto manufacturers are doing.

But tractors are not meant to run where cars do, like cities, villages, crowded highways...
I mean, could you expect tractors to stay in an area with stable mobile coverage? Or aren't they meant to run on vast rural emptinesses where you haven't (almost) any?
In any case, a Faraday cage would help the owners in protecting their properties.
Again, a tech savvy owner has plenty of means to do it.

Comment How would they do that? (Score 1) 491

I wonder how can John Deere remotely lock a tractor.
I see only two options:
1. They install a mobile modem (with sim) into every tractor or
2. They require the tractor to go online (via WiFi) every day or so.
In any case I see easy ways to circumvent option no.2. But with option no.1 they'd be assuming universal mobile coverage across all USA, which seems not to be the case...
