The excuse "I was trying to clean a dead bug off of my windshield and lost track of how fast I was going" didn't go over super well.  I was about to try "I still don't know the difference between kilometers per hour and miles per hour" but 133 mph is considerably worse than 133 k/hr so that wouldn't have been better anyways.  Luckily it doesn't really matter since I'm not planning to come back to New Zealand any time soon.  Thus there's no reason to actually pay the $300NZ ($200US) ticket.  It does make a lovely souvenir of the thousands of miles we've driven here though.
