Yesssss (fist pump) someone else who understands BEDMAS. I hope you added the bracketted figures first. My point is this: any Poindexter can dawdle along all day calculating if they should pass or not - ooooow ooooow don't forget to factor in ambient temperature, our last known tyre pressures and the tacho reading + our current gear. Blah blah blah, or would General Physics produce a far quicker result i.e. Foot goes down + Needle goes up = pass completed (result) THEREFORE (sorry no three dot triangle on myyyyyyy keyboard) Less stress, less time wasted, lean back.
Ignorance! Probably appears so to the science club. Indifference! Definitely, if you're gonna go, GO if you're gonna sit back there moaning, all the same to me, I'M going. My car > your car anyway square bahahaha

You have also overlooked all those "Slow Down!" signs.If drivers are doing the legal limit or lower, why do they need the signs!Lets face it, we all know that the higher the official speed limit, the fewer the cars exceeding it.
If the nanas are doing 80kph in a 100kph limit, then do you think they'll go any faster if the limit is raised to 110!All that would happen if they raised the limit is that the majority of driverswould just carry on at the same speed but there would be fewer breaking the law - a lot fewer.I would wager that the accident statistics would not be any worse either, as the drunk drivers and careless ones will still kill themselves (and innoccent others), as they are idiots anyway.
When you get to 110kph, or ideally 120kph, there is far more concentration on the road ahead.The idiots who wipe themselves out at 130/140kph will continue to wipe themselves out, regardless of the speed limits.
There are only 4m people in NZ and 60m in the UK, for a similar land mass. We can't claim that our roads are crowded - apart from one or two notable exceptions - yet their accident statistics, however you choose to interpret them, are a darn sight better than ours, even with the recent massive influx of Easten Europeans, burka wearers and ox-cart drivers.

pretty sure our miles-per-household is really high
your right about 110 or 120 tho - the road toll would be neglible in the difference. the highest toll ever was when we had the 80 km/h limit imposed on us
the trouble with a 120 limit is that although our roads are fine for it, you would still have 90 km/h trucks everywhere
we already have problems with 100km/h cars sharing the roads with the massive amounts of trucking we have - a 120 limit would make the problem worse

This was done on a trucking site for a car doing 103kph passing a truck doing 93kph. BTW i have never seen anyone overtaking me get a ticket and most people dont muck about, not only does the cop have to pass the traffic behind me he also has to pass my 20m truck safely even with flashing lights, by the time he has done this the offender is goneski! Just put your foot down and get on with it.
"Well lets assume that the truck is a line haul unit at 20 metres long doing 93 kph and the car is doing 103kph as per the new speed limits.
Lets say the car is right on the bumper of the truck and cant see past and hasnt built up any momentum prior to pulling out like the muppets normally do.
A second will be wasted as the car pops out and decides whether to continue or not and will travel 25.83 metres in this time in the oncoming lane.
These clowns usually have the flashest cars so we'll assume a miracle instant acceleration to 103kph, and that he will pull in right on the trucks bumper violating his safe following distance buffer zone as they do.
The car will be doing 28.61 metres per second at 103kph passing the 20 metres b-train unit. The truck will be doing 25.83 metres per second at 93 kph.
Five seconds after popping out the car is only 13.9 metres further foward from the back of the truck, about where your first trailer axle is. At this point the truck has covered 129.15m and the car has covered 143.05m.
It will take seven seconds to get level with truck bumper, truck has now moved 180.81m and car has moved 200.27m.
So lets add on another second for him to get fully past and back in lane plus the second at start for the pop out manouvere. So nine seconds in total in which the car will have covered 25.83 m plus 8 secs at 28.61m a total distance of 254.71 metres.
Assuming there is oncoming traffic in the distance doing the same speed of 103kph and who choose not to brake at all then the car needs 457.76 metres of clear road ahead once he has popped out. "

Yip I agree I wouldn't want to do 120 on some rural roads and typical state highways, thanks to transit for putting random plot holes in the road and appalling dips.

That is the whole point!We hardly need a speed limit on some roads as in many cases, even those of us with brisk cars are not going to drive any faster than is comfortable.If that happens to be well below the limit, so what!
We all know about the muppets who slow too much for no good reason but a brisk piece of overtaking soon despatches them - for good. Sprinting up to a good speed then dropping back to a comfortable speed, is so sensible and you are very unlucky if for that few seconds, you get pinged.

I dunno why people don't get this, an engine operates at a particular optimum revs and efficiency along with the gearbox. There are pumping loses, cam profiles and all sorts to think about. Compare foot flat in 5th up a hill to half pie throttle in 3rd, one is doing more revs but is still more efficient. My dad's amg merc cruises quite nicely at about 140 cause the gearbox has huge long ratios on it for euro cruising.

I would like to see a law passed where cars being overtaken in a passing lane can not exceed 90km/hr. So that would give the passing vehicles a 20km/hr tolerance to overtake.
Also should outlaw accelerating while being overtaken, hard to enforce but should hopefully discourage a few idiots.

your maths is probably dead right , but don't forget to add another 100 metres of clear road AFTER the passing manouver is completed (a total of 557.76 m) as required by law but largely ignored- a likely reason for many head on smashes or near misses. The most likely reason for drivers passing trucks is because of the restricted visibility due to big rigs on our mainly narrow state highways.

it is against the law to accelerate while being overtaken! Do you have a drivers licence!
johnf_456,
Mar 26, 9:33pm
Not all cars are efficent at 110 yes some are but not all, especially older 4 speed manuals or even 3 speed autos and some 4 speed autos with poor ratios.
If not where is the legislation which makes it illegal to accelerate while being overtaken!It gets a brief mention in the road code, but thats a guide which reflects the legal requirements but is not legislation in upon itself.
pollymay,

I was more getting at the people that solely believe slower = more efficient. Just like the ones that think fuel is totally dependant on revs not air ingestion of the motor as well as piston cooling needs which depends on timing curve which depends on throttle position and airflow into motor which depends.etc etc.

What a load of hilarious dribble this thread is. At 110 k's just about every single car on the road will be using more fuel than 100 k's and a huge amount more than at 90k's. Average increase from 100 to 110 km/hr is 13%. I hope none of you speeders ever complain about the cost of fuel, and take a ticket on the chin when you get one. The law is the law, just chill out and listen to some music in the car, dont stress just cause you cant get passed someone. Who gives a rats if you take a few more minutes to get where you are going. And if you continue to speed i hope you do get caught. Suck it up, youre in the wrong if you are breaking the law.

I pass, if they speed up then I pull in where I would've pulled in if they'd maintained their original speed. Normally this results in lights and fingers but signalling to them to pull over and sort this out on the side of the road usually results in them dropping back to their original speed again. But back to the original thread: If you're gonna' go, go.

I've beenin a queue of cars entering Tauranga (about 6 of us) all doing 125km - didnt even notice, until a cop went passed us and kept going. Only reason I can see why he didnt stop any of us cos it was all of us, not just one person blasting along.As soon as I get stuck behind ONE person who does not do 100km I will pass them no matter what at the first passing lane (yes they are the morons who speed up so I speed up more). I have also never been ticketed for speeding and hardly ever see Police while openride driving - apart from that Tga cop who didnt stop.

Obviously another Luddite who hasn't driven a modern car with an actual fuel use computer.It is NOT more economical at 90kph than 100kph in most modern cars with a 2+ litre engine. In an older, smaller engined, low gearedcar needing to rev its socks off, to overcome the drag and lugging around the cast iron engine and the aerodynamics of a skyscaper, totally agree, but technology has moved on.
Maybe if you charged by the minute, you'd realise that travelling at 10% or 15% slower than you legally and safely can, costs the customer 10-15% more - and they don't really like that.
"Oh sorry sir, I'm afraid the travel portion of your bill is $50 higher than usual, as I decided to chill out and listen to my music and just cruise at 50kph rather than 100kph."
If 100kph being the maximum speed limit represents an efficiency rating of 100%, then 75kph represents 75% efficiency and that ain't gonna happen and is not accetable.Of people wan't to tour and see ythe sights, takeabus or a train.If you choose to drive on thew publicroads, then you owe it to other road users to drive at 100% concentration- regardless of the speed and preferably at 100% efficiency too.
If someone comes up behind me at over 100kph and wants to pass, I move over.He has to justify to himself his reasons for breaking the law,He doesn't have to justify it to me. As long as people don't lose control and can safely stay on their own side of the road, use their mirrors and move over to let others pass, all is sweet.

Personally when i get to a passing lane. i just nail the throttle and dont get off it till im About level with the lead drivers B pillar. If im passing a line of cars i could be doing god knows what. As far as this im concerned this is the safeist way because everyone behind me gets to pass as well. which they wouldnt if i stuck to 110.If the police fine me, ill just wear the fine. Although most police tend to take a commonsence approch in this area. However fixed and moblie cameras will not abide commonsence. As for drivers who speed up on passing lanes. Alot of drivers(hawkes bay was particulary bad). Dont feel safe at 100k. But they do feel safer on straight flat or wide pieces of road. so they speed up.They uasually say something along the lines of "oh 95 is more that fast enough""people are in too much of a hurry" sorry but anything im doing is important enough to be in a hurry. even if that something is nothing.im looking foward to meetingthe oncoming car which has just passed one of these people on a blind corner. If someone doesnt feel safe doing the speed limit then they should hand their licence in. Rather that trying to kill the rest of us by causing other drivers to take risks getting past. As for fuel use vs speed. Who cares.if you dont believe the skys falling on our heads due to car emmissions. Id pay 4 dollars a letre if it keeps me away from public transport

Suck it up, you are some totally and completely wrong you have no idea.
I would have no problem with low tolerances if they were used to enforce moron driving. Instead they are using them on people not doing anything dangerous, so far as I'm concerned they can stick their tickets. Point out totally dangerous driving and they shrug their shoulders, crappy policing on top of bad policies.
