Much of the process of driving from one place to another is instinctive - we don't always consciously tell ourselves to change gear, indicate or give way because these actions come naturally. We are fine-tuned to the process through years of driving.
In a few weeks we'll be putting that instinct to the test.
One month from today New Zealand will join other countries which drive on the left, including Australia, Britain, Ireland, Singapore and Japan, by switching to a system in which free left turning traffic has right of way at intersections.
Since 1977 New Zealand drivers have operated under a system I've seen described as "treating every uncontrolled intersection like a roundabout", or as was taught me as a learner driver, give way to traffic on your right turning right.
It's not just uncontrolled intersections that have needed attention though.
