Maybe tractor hacking will become a thing, too. I know lots of guys who circumvent the computers in their cars with pirated software, to make them racier. Might be a career in it for some of them.
Also, I haven't bought a new car in many years. Is there something like a EULA buried in the small print? And I don't imagine buyers on the secondary market sign anything. Or will it become illegal to sell used cars because the software license doesn't allow for transfer?
In the EU? Only if TTIP gets signed.
