Personal anecdote, we flew into Narita and the customs line caused us to miss the bus that would have connected us to Haneda for our next flight. We were certain we would miss the flight, but instead we got one of the best taxi drivers I've ever met. From what I gathered, in Japan you basically pay a set fine for travelling over a certain speed. So he added that into the fare (vaguely recall it was 15% or so). Long story short, after some very impressive driving we got there in time. I gained a massive appreciation for Japanese taxi drivers that day.
