DAMN IT! my post was erased...
here's the rundown:
hi old buddy, thanks for the welcome, nice to see you too
your analogy is correct. but yes, you do have to prove you aren't intoxicated or you're screwed. Walk the line and blow/test clean or you're through. refuse to blow in the tube and it's auto suspend--no trial necessary
I agree with you that these types of things are criminal in nature. and in case I didn't make it clear enough, my friend and I think these types of things are just end-arounds to the traditional protections afforded criminally accused. don't like it personally, but people are happy when the dope doesn't get bought and sold, and they're upset when they are confronted with the implementation of their idea that criminals should be hooked and booked without regard for their "rights" (rights? what rights? what about "victims'" rights? ...see, this isn't a new mantra)
but the direct answer to your question, I think, should be that if you are compelled to drive around with a hundred grand, packed in foil, hidden in a cooler, stuffed in a trunk of a rental car in someone ele's name, then:
a) don't lie about it to the cops
OR
b) given that you didn't follow a), don't grant the cops consent to search the car for fuck's sake
