I wonder tho, if a corner has a posted speed of 45 and I come around it at 70-80 would they care? 

 

 

The ones on corners are only recommended "comfortable" speeds, not legal limits. I find you can  add 20km/h to them and still be comfortable... 

 

 

 

 

I know they are comfortable recommended speeds but if i flew around one would they try to nail me for careless use of a motor vehicle or alike. As long as the rear doesn't break loose..

What I find interesting is that in NZ it seems like all the speed cameras and other police equipment is supposed to be accurate enough that +4 km/h is actually reliably measurable.

 

Fun reading:

 

Questions raised over accuracy of speed cameras after driver doing 29mph was clocked reaching 85mph

 

 

 

Police.govt.nz claims:

 

"How accurate is the equipment used to enforce speed?

 

Transport law requires all speed detection equipment, including safety cameras, radars, lasers and vehicle speedometers to be checked (calibrated) and certified every year.

 

Any new camera is subject to a rigorous testing and approval process before being used."

 

Notice how they don't actually answer the question? No accurate to x km/h or a percentage. Just "We test our equipment".

I get up to 4 different speed readings when driving my car - 

 

Speedo reads high, around 10% +/- a bit based on the GPS speed indicated on my radar detector and/or GPS on Waze on my phone. The speed on my radar detector is 1-2 km/h lower than the GPS on Waze app on my phone. All three of these are higher than the speed sign as I approach the 50km/h limit heading into Lincoln where I live.

 

Which one is accurate? Absolutely no idea, if I get ticketed for exceeding the speed limit by a camera van, first off I'd be annoyed that I was driving with my eyes closed that I didn't see it before it got me

It seems that some people miss the message every year.

That info could simply reflect traffic volumes ... ie more total tickets issued because more people are on the roads, rather than a higher infringement rate.

 

Tickets per total km driven by motorists would be more meaningful statistic.

 

Ditto road toll.  Best statistics are casualties per billion km driven.

 

 

I don't believe our roads (in Auckland) have the capacity to have that scale of volume increase. Just the increase from school hols to not school hols just about stops the roads from moving. In other words a very small volume increase and there's zero chance of breaking the speed limit due to congestion.

Had been in the Wellington area (moved down from Napier) for about 5 minutes before getting a ticket there..

This still amazes me -- I never see anyone speeding up/down the gorge (in fact, you see everyone has learnt to brake at the appropriate time...). Perhaps it's catching tourists/non-locals rather than the locals who probably avoid getting caught daily!

I wonder if police cars are GPS tracked for speed. I was following one through Dome valley on Sunday at a constant 95 and in some spots he was up to 100 and i kept 50M behind him the whole time and speed matched him. No lights or sirens displayed, he didn't seem to care about me. 
Nailed him in the overtaking lane too around the bend at the top heading south. 

 

I wonder tho, if a corner has a posted speed of 45 and I come around it at 70-80 would they care? 

 

 

if they have radar equipment they have their speedos regularly recalibrated as it impacts the radar.

 

the posted speed on corners is for a fully loaded truck, not for a light passenger vehicle + they are only advisories.

And that's a nonsense that really irritates me... "safety cameras". Do they seriously think that if they repeat it often enough that it will make a jot of difference? Or do they really believe that they have any impact on safety?

 

NewSpeak at its worst.

I give it half an hour before this thread stoops into a pointless discussion over 'quotas', tourist drivers, 'I know my car and my driving skill so I should be able to go quicker than that', comments about other driving behaviour which is *never* targeted and all the other jazz which always derails discussion even remotely connected to law/policy/driving.


As OP said, this is bulk standard now and has been for years. Anyone who gets a ticket deserves it, end of story.



You might be wrong. Revenue gathering is what you are thinking of.

kingjj: We love to be on a high horse on GZ, in part due to the huge community of well educated experts that come here. Issue with someones internet? Should have picked a better ISP. Malware issue? Should have had better security processes. Involved in a car crash? Should have driven safer.

 

 

I will fix this for you...

The number of drivers who are incapable of using turning and merging lanes, and who seem completely oblivious about who is behind them and what speed they are actually driving is unbelievable. How many times have you followed someone doing 80 - 90, then the moment the road widens and there's a passing lane they nail it to 110, then back to 80 - 90 after the passing lane. Does my head in. 

 

 

I'd like to see police stop people who do not indicate, or indicate the wrong way in roundabouts, or speedup when they see someone merging from a motorway entry ahead of them instead of changing lanes. I'd like to see police stop people doing 80 on the right lane on a multi-lane motorway. Or people who do 100 but do not change back to the left  lane even after they passed someone.

Not sure why you would have a tolerance any higher than 4km/h at any time. I have seen more muppets on the road in the last week than I have in the last 3 or 4 months, it's just getting worse and worse, there doesn't seem to be any decent form of maintaining the rules of the road.

In my experience most people abide by the speed limit. A LOT of drivers travel 5 to 10 KPH below the limit, I suspect due to speedometers that read high. I know how my speedometer compares, I've checked it using several GPS units and it's always within 1 KPH.


All the 4 KPH tolerance will do is cause long lines of traffic and frustrate drivers stuck behind slow traffic. The end result is drivers overtaking in silly places, hardly a safer situation than sticking with the 10 KPH tolerance.


Some drivers will be watching their speedometer unnecessarily and not keeping an eye on the road and other cars. As a result they will end up driving slower than they would do otherwise. 


Other drivers will not pass as they are afraid of being caught busting the 4 KPH tolerance, or they will pass but do so at such a speed that they take up all the passing area and prevent other cars behind them from being able to overtake. The less time you spend on the other side of the centre line the better, so within reason the faster you travel while overtaking the safer you are since your time exposed to danger is reduced. The 4 KPH tolerance doesn't provide for you to do this.


Of course the slow drivers inevitably speed up when there's a passing lane then no one passes for fear of being caught speeding.


In my opinion the 4 KPH tolerance is just "There we've done something to reduce the road toll", window dressing.

In my experience, those who travel just above the limit, are the ones that are most likely to get penalised. Those that travel at light speed, probably don't get caught.
