This is an extreme case, because GM has had virtually no presence in Japan and pulled out of Great Britain five years ago. Without really big RHD markets to generate big volume, RHD cars are not sustainable. Which is a worry for the rest of us, because no global car company has ever made a car just for the minuscule NZ market and no global car company ever will. We have to take what's available to other markets.
If we want to be guaranteed a vibrant Kiwi car industry with lots of consumer choice, we need to make the move… to the other side of the road.
Scared? Don't be. It's perfectly do-able and it just makes sense. It's been done before.
In the 1960s Sweden proposed a change from RHD to LHD to better align with Europe. Although over 80 per cent of the population were opposed, it happened anyway – in September 1967. It's never looked back; or if it did, it was over the other shoulder.
More recently the independent state of Samoa also changed sides, in September 2009 (September seems to be the month for swapping sides of the road). It actually went the other way, from a LHD infrastructure to RHD, to better align with NZ and cheaper affordable used cars from Japan. But it's further evidence it can be done. It's okay – it can always change back.
In case you're wondering why the world couldn't agree on where steering wheels should be in the first place, the RHD scenario was actually first. In feudal times, it made sense to walk or ride on the left-hand side of the road, as that left your stronger right hand free to fight when necessary.
But in 1700s France and Germany, goods wagons were often hauled by teams of horses and the driver sat on the left-rear animal, to keep that strong right hand free for lashing. So it was better to move to the right-hand side of the road.
There's also a story (possibly apocryphal) that wherever Napoleon came and conquered, he forced people to change from travelling on the left to travelling on the right – just because he could, as a show of power, but also because he was left-handed.
On second thoughts, maybe the rest of the world should change to RHD.
