Wow, I had no idea those Japanese cars had drive by wire and not a 
conventional steering system. That would scare the heck out of me.  
Can't stand to fly in jets with just fly by wire systems. I like the 
hybrids myself.

If you're concerned about RF getting into the computers on the car, what 
if you have one and are driving next to some guy with a high power HF 
station in his car on the way to Dayton? You not only have to worry 
about your own transmitter, but also someone else - or what about 
getting close to a commercial transmitter?
