The speed limit poll

[Maha]

....yet another inane poll that results in little more than keyboard/forehead damage.

Heya, let's get some quantifiable opinions on +4 kmh vs. 10 kmh debate. Coz I just frankly don't give a shit. If I speed it's never +7.5. if I'm going home after ride I do 100 coz I can put my feet down....

It's hard to argue that the reduction to a +4k tolerance from a +10k tolerance doesn't work - there were ZERO fatal road crashes over the Q's birthday weekend. That's a hard quantifiable result that is difficult to argue with ... (not impossible, just difficult .. I accept that there are many many valiables and speed is just one ...)

While I agree that speed doesn't necessarily kill, that means there were an awful lot of cages going slower the past weekend - and given the skill level (non-existent) of the average cage driver, slower cages has got to be a good thing.

I'm particularly interested in where the fatalities are.

The best stats I've found so far are NZTA published by city and district for 2009.

For example - it appears head on collisions as a result of misjudged overtaking are far fewer than head ons caused by just being on the wrong side of the road (drifting over the centre line, cutting corners etc...)

I am particularly interested in why the police seem to focus on the Foxton straights. that's where I saw most police presence over the weekend (basically none other than the foxton straights). I wonder whether the accident and casualty rate really means its a dangerous stretch of road or just a convenient road for road users to speed and therefore earn good government revenue

It's very easy to argue against that using basic statistics. To say it was the result of the tolerance change you'd need to show a significant change in the stats. That's using the statisctical definition of significant, ie a result that couldn't be explained by normal deviation.


This weekend could quite easily be the result of standard deviation. Plenty of weekends have zero road deaths throughout the year, granted not many of them are long weekends, but it's not beyond the realms of probabilities. Especially if you factor in things like the price of petrol, the economy (incl chch quake), and the weather.

Otherwise I could prove the tolerance has no effect because last years Labour weekend toll was unchanged from the year before. Therefore, it does nothing.


The only way to argue convincingly that the zero road toll was a result of the speed tolerance would be to measure over a decent sample and see if there is any significant variation. I'd suggest if you did that there would be little evidence.

I'll have you know it can reach 175 with a good tail wind! Not my fault licensing system means I have to wait 2 years for something bigger than a 250

i'll have you know thats bullshit and your 175 is much closer to 150.

I can't help it has such a small displacement!

Love the way they worked the motorcycle in to that article, so what if it was on a trailer. It implies the driver of the ute has something to do with motorbikes so must be bad.

I thought speedo error was up to 10% and that that was why they set their mark at 110. $16billion in the red = they are after more cash = 104 limit.

Well you are certainly going to get some biased statistics here...

[Brett]

I ride to the conditions...

When they change do you reduce your speed?

[oneofsix]

you sound as bad as the NZTA ad. What if the conditions get better? do you still want him to slow down?
If you ride to the conditions it means you adjust your speed, up or down, as the conditions change.

I'd put some serious money on a good few of us here (and elsewhere) needing to address some other significant issues in our riding and driving before we can complain that the limit is unfoundedly reduced a few kilometres per hour.

The "lolz if I speed it's way over 104kph anywayz!111!!1~~" crowd gets first mention.

Yeah I should have totally added detail, 150 with my knee down on a road I'd never previously ridden on during peak hour in heavy fog.

Grow up.

And even then you'd have to eliminate all other possible causes. Correllation does not mean causation.
