This is so true, and it's surprising how many people don't know what they are obligated to do when asked by an officer. It's even fuzzy for me at times.
It should be well known that you are required to show ID if pulled over [Whren v. United States (1996)], your passenger is required to show his or her ID [Brendlin v. California (2007) & Arizona v. Johnson (2009)] , and you must exist the vehicle if asked to do so [Pennsylvania v. Mimms (1977) (for drivers) & Maryland v. Wilson (1997) (for passengers)].
All of these requirements have been litigated to the supreme court. You should also know the difference between probably cause and reasonable suspicion. We should add these topics to high school civics or something.
