Civic Duty: What exactly is Caeser's?

I was driving today when it occurred to me that I had no idea what the date was.  Instinctively I grabbed my phone thinking I'd quickly check the calendar.  As soon as I picked up the phone, I heard a sharp honk from the car next to me. I looked up and saw an older man in a minivan shake his head at me. I got the message. "Put down your phone while you're driving."  Embarrassed, I dropped the phone like it had just bitten me.  I had two thoughts 1) I was surprised that he would take the responsibility of warning me to stop doing something so dangerous and 2) running through moral theories, I concluded that he had a right to tell me to stop "texting" because he was also using the road and I was potentially endangering his life. 

I had an immense amount of time on my hand (it's a long drive to my parents house.)  So, after watching this minivan driver go above and beyond, my thoughts naturally drifted to the subject of Christian civic duty.  Where does it start and how far does it extend?  The easy answers are either Christians are called to obey every law  (throw in a "Give unto Caeser" reference here, see 1 Peter 2:13, and  then spend some time visiting Romans 13:1-7).  Or, the other extreme,  Christians are only beholden to God's law; all other laws are outside the realm of Christian duty (cling to Acts 5:27-29).   Surely, neither option is right.  Neither extreme can fully capture what the expectation set in the Scriptures. Can they?  

The first option seems to call for blind Christian obedience to every applicable earthly law.   Laws (and, trust me, I know something about this--I play a lawyer on tv.)  are written by a random assortment of lawyers, business men, activists, teachers, and you name thems.  As a result they're sometimes dumb, badly written, amoral or just wrong. 

Let's discuss the most entertaining: Is it God's expectation that we follow dumb laws?  An internet search assures me that in Eureka, IL at one point it was illegal for a man with a mustache to kiss his wife.  Was every mustached man who refused to shave before he kissed in violation of God's word, because he was breaking Eureka law?  And, was his kisee wife also culpable?  Arguably, the man could easily shave in order to be in compliance.  But, the question is: As a Christian, does he have to?  (And also, does Mrs. Mustache have a Christian duty to Heisman Mr. Mustache whenever he leans in?)

The second extreme says Christians are not required to follow earthly laws.  That is, Christians only have to adhere to rules explicitly listed in the Bible.  This option is more of a problem for the well written, meaningful laws.  It's ridiculous to think God doesn't expect Christians to stop at red lights, serve criminal sentences, or only vote once during elections. 

That said, there has to be a middle ground, right? ...thoughts?
