I suppose if this was the late 50's, this would be awesome! Perhaps, in 
light of how bad it has gotten, nearly 3/4 of a century later, it's time 
to review the decade old standards, and come up with some real-world (as 
of this time, and reasonably foreseen) requirements, with a reasonable 
limit on strength.  Old junk electronics will die off, new stuff can 
meet a better standard, such as we are learning with plasma TV's.

Speaking of which, I have a new to me, relatively modern vehicle, that 
is an RFI/EMI cesspool.  I'm envisioning sheathing the wiring in EMI 
tape and bonding everything I can.  I'll have to jump into SDR with both 
feet as hearing a few kHz at a time with an HT, or even seeing a few MHz 
with an HP, or Singer spectrum analyzer is no longer sufficient, I want 
to see many, many MHz at a time, in real time, and also have the ability 
to sniff individual wires/harnesses/modules.  It should be fun, and if a 
hobbyist can do it after the fact, those in the industry can achieve it 
during the design phase.
