[quote:533bdf0724]If you are the one turning left, who has to wait for the other cars turning right, you can still nip around the corner if they are held up waiting for a gap in the oncoming traffic.[/quote:533bdf0724]

i think the theory is though, that by giving way, you provide that gap thereby reducing the number of cars queueing up behind the car waiting to turn right.

I think its a great rule.

I've noticed in spain that they dont like that situation to arise. so much so that they put signs up in certain places saying no left turn (remember they are south paws in spain) so you then need to go along the road to either a round about (or a slip road sometimes) so that you can then come back and turn right without holding anyone up.

Fantastic idea.
I wonder how many accidents in Britain are caused when a person is waiting to turn right off of a main road and some berk' not watching whats going on slams right into the back of them.

Much reduced in NZ or spain I would guess.
