I reckon the Government’s argument in favour of increasing speed limits is looking more and more wobbly.

There’s no question that it’s going to happen, with Transport Minister Simeon Brown confirming at the weekend that faster speed limits will be all-go next year. 

But it seems to me that his case as to why it’s needed and why it’s a good idea, is starting to look pretty weak.

There’s an expert who is trying to sell an alternative idea which will probably have Simeon Brown laughing his head off. He’ll think it’s balmy. But I reckon it’s got some merit to it.

Simon Kingham is this expert. He’s a university academic and he used to be the Ministry of Transport’s chief science advisor. 

He’s saying that, instead of increasing the speed limits, the Government should be setting the same speed limit for every vehicle on the road.

That way, there wouldn’t be any need for cars to overtake trucks because - and for drivers to increase their risk of death or serious injury - because everyone would be doing the same speed.

This is his solution to an issue the outfit representing the trucking industry has highlighted. Which is the fact that when the speed limits go up next year it won't be for every vehicle on the road - and the maximum speed limit for trucks will stay what it is now. Which is 90 kph per hour.

So, cars will be going faster. And trucks won’t. And Professor Simon Kingham says, all that’s going to do, is encourage more drivers to overtake and more people will die, as a result.

He says if everyone was going the same speed - no need for any risky overtaking maneuvers.

And I think, on paper, he’s right. On paper, it sounds like a great idea. 

But, the reality is, people are idiots. They think the fast way is the only way. And, even if cars and trucks had the same speed limit, drivers would still gun it well into the hundreds.

Can you imagine, at the peak of summer, people being content to sit behind a truck all the way? Of course they wouldn’t. Because it’s all about getting there as soon as you can, isn’t it?

There’s none of this “life’s all about the journey” talk once kiwis get behind the wheel.

So, Simeon Brown’s not going to be liking what the professor is saying today about having the same 90 kph speed limit for every vehicle on the road.

I’m picking he’s also not going to be liking everything the trucking industry is saying today, either.

Because remember how he’s been banging on about how increasing speed limits is going to get us all going faster and it’s going to increase productivity blah blah blah.

But, when it comes to productivity, that won’t be the case at all.

Because, as the head of the outfit that represents the transport sector, Transporting NZ has confirmed the speed limit increases will have no direct impact on them because trucks will still be restricted to doing 90 kph.

But where Dom Kalasih does see benefits in cars being allowed to go faster, is that he says drivers will be able to pass trucks more quickly. Which he reckons will reduce the amount of time car drivers spend in risky situations.

He does concede, though, that if the cars are going faster past the trucks - then any supposed reduction in risk might be outweighed by the fact that drivers are going at higher speeds which, of course, increases the chance of something going wrong.

So, as far as I’m concerned, I see these increases in speed limits confirmed by the Government as a lose-lose.

I also think that this idea being floated by this academic today is a win-win, but only in la-la land.

And we’re not in la-la land.
