::Twisted pairs are actually pretty well self-shielding and immune to reception and radiation of RFI.  Hard to believe anyone would try to market an automotive vehicle that won't work when parked at a mountain transmitter site that's home to 20-30-40-50 50kW-250kW TV and FM BC transmitters, or at a field site that's home to a 50kW AM BC transmitter.  You can generally pull right up and park next to any of those.  Not to mention the numerous 1 Million Watt e.r.p. SW BC transmitters that are found all over the country, and the world...

Actually, this may not be as farfetched as all that - if I remember 
correctly, some late-model cars are now using ethernet for their data 
communications between the computer, various sensors, and various 
actuators.  I have no clue as to the degree of built-in EMP protection, 
particularly in vehicles with plastic body panels, or the potential effect 
of RFI.
