This has worked for me in the past (gotten off with only a warning). Along with the hands on the steering wheel, engine off, interior light on, window down I might also add, ask the officer if you can reach for something before doing so.

Cop: "Can I see your license and registration?" You: "It's in the glove box." Cop: "Go ahead and grab it."

It's not about submitting to their authority, it's about doing things that benefit you in the end. You don't have to do any of this stuff, but don't complain when things don't go your way.
