Linux:

@tweake Not the point cars should be moving left! They are breaking the Law

while traffic is required to use left lane unless its full or your overtaking the traffic. if the left lane is not full you can simply overtake on the left. either way demanding people to get out of your way is pointless.

I believe the NZ rule for speedos is the indicated speed can be up to 10% +4kph of actual speed. A car with the speedo reading 100kph can actually be travelling at only 87kph.

Speedo is not permitted to read low.

My work Toyota speedo reads 100kph at 94kph, so I normally cruise at 106-108kph on the speedo. I have a GPS app on my phone that I often use on trips.

Journeyman:

If you're in the right hand lane and people are tailgating you, either speed up or move over to let them pass.

@newtogeekzone

kiwis tailgate to be abusive. its got nothing to do with wanting to go past, i've reported plenty for tailgating on empty passing lanes. unfortunately kiwis have major issues with domestic violence and attacking strangers.

From NZTA website;

"Keeping left on a laned road.

Most roads in New Zealand have lanes marked on them with a white line or raised studs.

When driving on a multi-laned road, it is important to drive your vehicle within your lane.

Where there are two or more lanes on your side of the Centre line:

keep in the left-hand lane as much as you can (this reduces the risk of drivers being in your left-side blind spots)
keep in the centre of the lane, as the camber of the road can tilt your vehicle.
don’t use the lane closest to the centre line if you will hold up other vehicles.

The lane closest to the centre line should only be used when:

you want to pass another vehicle
you want to turn right
the left-hand lane is full with other traffic or is blocked
signs or arrows direct you to (eg signs direct heavy traffic using the Auckland harbour bridge to use the centre lanes)."

the rule is it can read up to 10% higher. many manufactures exploit that to make people drive slower to give better fuel economy. if you look at what the speed the ecu sees its often bang on. its only the display which is programmed to display incorrectly. another trick is that its not a %, some will read accurately at 50kmh but not at higher speeds.

the +4kph is not a rule, its simply a made up number to what the police might start enforcing it. its used to be 15kmh over, then 10kmh over, now 4kmh over, now 0kmh over during holidays. all depends on where and when, and if the cops in a good mood or needs to fill his "quota".

for those quoting sources, keep in mind things like road code and NZTA are not the actual rules. they tend to say whats good practice not whats legally required. for eg they had certain rules for many decades BEFORE there was ever a legal rule. people would get annoyed seeing people break said rules, even tho the rule never actually existed.

keeping in left lane as much as you can is clearly not a legal rule. laws are not written as bad as my writing.

"AA Motoring Affairs expert Mark Stockdale explains.

“International law has long required modern cars to overstate true speed. The applicable standard for most vehicles sold in NZ is a European standard that specifies that speedometers must not indicate a speed less than the vehicle’s true speed, or a speed greater than the vehicle’s true speed by an amount of more than 10 percent plus 4 km/h.”

What does this mean in real driving terms?

Well, another way to look at it is, at an indicated speed of 100km/h, the vehicle's true speed must be between 87.3 km/h and 100km/h."

I’m keen to know which, if any, iPhone GPS apps show speed in NZ. Google Maps doesn’t.

Sometimes I just sit and think. Other times I just sit.

it depends on what market and what rules they follow.

AU changed in 2006 from 10% to 10% +4kph which is eu spec. we tend to follow a lot of their rules and frankly a lot of our cars are for the AU market. however we also get a lot of japan spec models. i'm not sure what their rules are, but i have never seen any car with 10%+4kmh. i'm sure there would be an outcry if peoples cars where reading 100kmh at 87kmh.

As in limit you are in, or current speed.
If you have an active navigation point to point running on Android google maps gives an on-screen circular indicator.

Waze shows you the speed you are driving.

Oblivian: If you have an active navigation point to point running on Android google maps gives an on-screen circular indicator.

Maps might do that on a phone; but it certainly does NOT do that on the Android Auto screen built into the car.

Waze and Sygic both display "current" speed on the Android Auto interface; Waze can also show what the limit is (subject to data accuracy, of course - roadworks in particular don't normally feature). I can't recall if Sygic does or not now.

keeping in left lane as much as you can is clearly not a legal rule. laws are not written as bad as my writing.

In this case, it is an actual Rule:

2.1 Keeping left
(1) A driver, when driving, must at all times drive as near as practicable to the left side of the roadway unless this rule otherwise provides.

(2) If a driver’s speed, when driving, is such as to impede the normal and reasonable flow of traffic, that driver must, as soon as is reasonably practicable, move the vehicle as far as practicable to the left side of the roadway when this is necessary to allow following traffic to pass.

(3) A driver may drive in the right lane in the direction of travel when driving on a multi-lane road if—

(a) the driver is turning right, or making a U-turn from the centre of the road, and is giving the prescribed signal of that driver’s intention to turn right; or

(b) the driver is passing; or

(c) the left lane is unavailable to the driver; or

(d) the driver is required by any provision of this rule to drive in the right lane; or

(e) a variable lane control downward-facing arrow sign indicates that the driver must drive in the right lane; or

(f) the driver is avoiding an obstruction; or

(g) the traffic in all other lanes is congested; or

(h) the traffic in every lane is congested.

This is an actual legislative requirement that must be followed; the Land Transport Act 1998 gives the Minister for Transport Safety power to make secondary legislation (rules, regulations etc.) within certain boundaries.

In Australia you will get a ticket if you sit in the right lane unnecessarily. A pity the same doesn't happen here.

yes.

now keep in mind the bits i put in bold there is where the wheels fall off. there is no definitions for any of that and is highly subjective. there used to be at one point impeding traffic was having more than 6 cars behind, which is laughable these days.

people who want to push through traffic will always claim the other lane has no traffic hence move over, while your in fact passing all the traffic. if there was no traffic you could pass on the left. just like "pull over to let traffic pass" when there is no left to pull over to.

its a good example of bad law that allows itself to be misused. unfortunately thats exactly what people do. its all just ends up being an excuse to go attack people.
