VTNZ general manager of operations Gavin McNaught said: "In a busy metropolitan area, test applicants will be presented with a greater number of, and more complicated, traffic interactions than if in a quieter urban area.
"The increase in traffic interactions inadvertently increases the likelihood of errors."
If there are drivers in Rotorua who only passed their driving test because there were no or few other cars on the road at the time, Rotorua's higher-than-average pass rate is not something to be lauded.
In fact, it could explain why so many drivers I've come across in Rotorua take dangerous gaps at intersections and don't know how to let merging traffic in.
While I certainly don't claim to be a perfect driver who's never taken a stupid gap, I know I could pass a licence test in Auckland traffic because I did.
Learning to drive in Auckland meant I was taught skills like crossing a busy four-lane motorway, navigating a three-lane roundabout and merging into a long stream of traffic.
But I am sure, based on what I've experienced on Rotorua's roads, there are people who have never had to learn these skills and that makes them a real hazard to those sharing the road with them.
Perhaps the solution is to make licence tests longer and more difficult in cities with less traffic to make up for the discrepancy?
There will be those who think that's unfair but remember, getting a licence is a privilege, not a right, and should be treated as such.
