A strange rule in New Zealand is the "give way" rule for turns.
Two cars are approaching a side street from opposite directions. The car turning left must give way to the car turning right.
To cast it in driving on the right terms:
Two cars are approaching a side street from opposite directions. The car turning right must yield to the car turning left.
I think the idea was to make right turns (across traffic) easier. The main problem is that Kiwis don't use their turn signals any more than anyone else. Yielding to someone who's turning in front of you is a problem if you don't know they're turning.
