It depends on whether I am confident I am complying with the law. I used to drive for a living, so I can tell you, from vast experience, that cops don't bother me in general, unless there are issues - such as speeding, expired tags, etc. A jolt of adrenaline? Yes, in varying degrees.

Tell me, when on someone else's property, and you see security personnel (or the home owner with a gun), do you feel a jolt of adrenaline?

If your answer is no, bear in mind that your answer is only given within the experience that you are living under the greater umbrella of the host nation's set of laws, and the police to call upon. Try living in your proposed world, and then try giving a "no" answer. Bear in mind that you have never yet lived in your proposed world, and cannot say from experience what kind of adrenaline you might experience upon such an encounter. I think it stands to reason that it would be at least what you feel upon seeing a cop in your rear-view mirror.

If your answer is yes, then touche.
