1080p: This rule change makes sense. The current system is illogical.
The worst thing about the current rule is that both parties, the left turner and the right turner, both need to correctly anticipate the actions of a third party: the person driving up behind the left turner - will he wait behind the left turner, or will he overtake?
The other turning rule is even better to be getting rid of: when a person turning right out of a sidestreet has priority of the the person turing left into the side street. In the four years I've been in NZ I've never had a single person turning right into my side street give way, Is there a single driver in NZ who obeys it? I stopped obeying it after about a week.
