Mac,

I definately agree that as I understand their operation these commercial
passive jammers are totally without merit.  Maybe if you coated the car
with RAM it would stand a chance.  Simple things like the radiator are
pretty hard to cover with absorber and still have them function however.
It would take a lot of redesign.

I would still be interested in any references to the RCS of any car.

Personally I agree with you that speeding is an act of civil disobedience
and that civil disobedience is one of the better traits of American
society. And, yes, speed enforcement is used mainly as revenue enhancement
(for insurance companies also).  I was merely pointing out that a lot of
people have different levels of comfort in how disobedient they are willing
to risk being (sorry - bad grammer).  Hence the appeal of a "passive" (and
hence, legal) jammer.  That was the point of me asking the questions that I
asked - the appeal of a passive system could result in a lot of people
being ripped off and a clear articulation of why these systems can't
physically do what is claimed will hopefully help reduce the chances of
anyone being taken.
