I agree. The cop has the discretion to do those things anytime, but most won’t if you’re polite and respectful. In fact, most cops will go out of their way to be polite and respectful back to you.
Since you’re on a public roadway and your DL is a privilege, the cop has full authority and rights, under the law to question you. You have full authority to stay silent, but you can’t get mad if that backfires on you.
Oh stop trying to pick a fight. :-)
