Part of it is looking/being responsible.
If you're driving a nice clean car (eg. Lexus IS300, BMW 5/7 series, Acura), well dressed, clean shaven, older than ~27 etc. chances are that the agent who isn't a stickler will let it go past. BUT Try the same thing in a beat down Westfalia looking like you just got out of bed with crap everywhere in your car (fast food weappers, bags, etc.), and you're under 25 chances are even if you get a guy who isn't a stickler they'll probably think twice before letting you pass through with it.
