"Your Car Is An Extension of Your Home": What does this mean?

[68Charger]

No 5th ,it's a traffic stop Not a trial. You say minimal outside of DL, reg ins card. Polite chat, weather, time of day. Once you talk outside the box, anything you say that "isn't right" by LE standards. raises Flags. BG's stop, the guy raised numerous flags you could drive a car through. A suspect is fairly easy to see through once you've been around them. They are also uneasy around LE's it's that prison mentality, avoiding eye contact, looking at their feet, fidgity etc.

I was not aware our 5th amendment rights only applied to courtrooms...

My point is, you have the right to remain silent, and not incriminate yourself even if you're NOT under arrest... Use it. Lying is worse than shutting up... Even if you have " nothing to hide"
