Free Advice: if you get pulled over by the cops, they clearly have a reason.  Be nice, polite, provide whatever information the officer asks you.  You don't have to open a locked glove box or trunk.  Take your ticket and move on with your life.  Most of the time, you can dispute tickets in person in court and get out of most regular traffic tickets if you have a provable evidence or if the cop doesn't show up in court that day.
