Rodney Hide shows us why we should learn algebra at school

I was dreadful at algebra at school, still am.

I could never see any point to it, especially with the stupid questions like “if train A travels at 90km/h and train B travels at 100km/h and train A leaves station C and train b leaves station D at the same time will they both reach station e at the same time” or some other crap like that.

My answer, which turned out to be wrong every time, was “Check the timetable”.

I digress…Rodney Hide has shown proper use of algebra in slamming the Police’s stupid insistence on zero tolerance of exceeding the speed limit.

Overtaking on the road safely and within the law is now all but impossible.

The speed limit on the open road is 100km/h. The police are applying zero tolerance. You can now be ticketed at 101km/h. The speed limit for heavy vehicles and cars pulling caravans, boats or trailers is 90km/h.  

Do the maths. In good driving conditions we are advised to apply the “two-second rule”. At 90km/h that’s 50m. So you pull out 50m behind a truck and trailer, the truck and trailer is 20m long and you pull in once safely 50m past. You have to make 120m to pass safely.

If the truck is doing 90km/h and you stick to 100km/h it takes 43 seconds to gain that 120m.

At 100km/h you will have travelled 1.2km. You must allow for a car coming towards you at 100km/h. To pass safely you need 2.4km of clear road.

How is that zero tolerance going in achieving a low road toll this year?It is sitting at two so far…last year the total was seven.

The Police always claim success against speeding when the road toll is low…what will they do with zero tolerance and an increased road toll?

With New Year’s Day predicted to be wet and miserable I wouldn’t be hoping that it will stay low if I were them.

As much at home writing editorials as being the subject of them, Cam has won awards, including the Canon Media Award for his work on the Len Brown/Bevan Chuang story. When he’s not creating the news, he tends to be in it, with protagonists using the courts, media and social media to deliver financial as well as death threats.

They say that news is something that someone, somewhere, wants kept quiet. Cam Slater doesn’t do quiet and, as a result, he is a polarising, controversial but highly effective journalist who takes no prisoners.

He is fearless in his pursuit of a story.

Love him or loathe him, you can’t ignore him.
