The problem is people mistakenly believe that if they are cooperative with the cop, and that since they have nothing to hide, that maybe the cop will just forget about that speeding infraction you were pulled over for.

Not really, I live in Texas and they’ll just bring a dog and of course get a positive hit to search. Plus run everyong in the vehicle for warrants.
