US rules for 4-way stops are easier to deal with - if you are the first to come to a full stop you get to go first (people learn to judge that little jump on your shocks as you actually stop) then people take turns (N-S then E-W then N-S etc) - if it's unclear then the NZ-like rules take over.

Yes NZ has occasional pedestrian crossings, but not at the one place we most need them (roundabouts) - what we don;t have are ubiquitous ones (at every intersection)
