Police getting tougher on speed tolerance

[Mo NZ]

"At least while all these pedantic types are roadside asking for these documents the rest of us can rock on past'

The documentation will be available as disclosure. Usually takes a couple of weeks or so to arrive.
Copy of ticket, both sides.
Vehicle spedo cert.
Rader certs.
Daily radar check test results.
Officer radar qualified cert.
Notebook entries.

an accurate triangulation of locations in sequence) as it hadn't been used before.

triLATeration.
Fuck.

Authoritive??? Instantaneous??? Jesus Christ....

Anything produced in court as evidence by an appropriate party from suitable sources is deemed plenty enough reputable status behind it.
The case I watched the judge stated that speed evidence from GPS was already COMPLETELY accepted by the court but permitted the defence to challenge the location aspect (even though to get accurate gps speed reading it means an accurate triangulation of locations in sequence) as it hadn't been used before.

A radar on your timeline of reaction speeds might be instantaneous but then so is GPS. Depending on the system it might not be taking a measurement to the target as often per second but is still an accurate measure of the kilometres per hour travelled and therefore the rate of. A GPS as more authority too if you like as the data is 100% assigned to the target device/transponder via its serial number.
Police radar however does not designate its target, it merely indicates that an object in its field of view is travelling at speed x and this may be the target vehicle or a ghost reflection off trees.
Only military radar operating in Doppler mode can designate which object in the field of view is actually the one measured.

You can keep on not liking it but the fact is soon enough the GPS cellphone in your pocket will be your licence/ID card and personal policeman. In metro areas all the extra wifi locations will enable even further accuracy.

Nah, getting Jesus to take the wheel won't help you either.

Consumer GPS reads have enough innacuracy that the positions must be averaged to get a speed reading, so no, it is not instantaneous. In fact if you pull out and boost passed someone then slow down, the GPS will never record your true maximum speed. Additionaly, GPS has much higher altitude inaccuracy due to the angle it sees the sats at, so will often not read correctly going up or down hills (good thing cops never sit at the bottom of hills though eh ). And finally, fucking with the GPS data is pretty easy, if one could successfully protest a ticked purely with their own gps data, revenues would plummet; unless of course you sent them a whole days worth of data by mistake, right?

Wifi to enable further accuracy? surely you're not suggesting further accuracy is needed or attainable? I thought GPS was already the gold-standard speed reading

It's close enough to instantaneous when the offence is rate of X kilometres per hour not nano metres per nano second.
GPS will record close enough to your true maximum speed obtained, even during a brief overtake. I've ran the free app google my maps on my budget $199 smartphone in mountainbike park and recorded true top speeds on there as per what the handlebar mounted cyclometer says also. And believe me those top speeds are very brief, much less time exposure than say blasting past a car at 140 on a passing lane.
They do read close enough to accurate speed up and downhill, the difference is negligible as far as measuring in kilometres per hour and would be in favour of the offender anyway. In fact one of NZ's major trucking companies has ordered its drivers not to even exceed 90k downhill even for the briefest moments before a climb.
If you want to fuck with gps data (called tampering with evidence at houses of higher repute than yours) go for it....
The other thing about protesting a ticket via GPS is that once you announce that the cops have the right to examine ALL the recorded evidence not what you select. Eg you could not turn up to a murder trial and only enter certain pages of your personal diary as evidence to defend yourself, you'd have to table the whole book or file. And with holding the rest would be grounds for cops to obtain a warrant to see what you don't want seen.
The case I mentioned earlier was all started (in my view, could have been other reasons) by a truck driver protesting that his GPS said 96 when he got radared at 98. This then gave the cops the heads up/right to come to the workplace and demand the GPS records for that truck. He ended up very lucky (the files showed over 300 alledged speed offences) that the cops stuffed up on some technical court matters in the way they entered the evidence and case got thrown out.
The further accuracy is not needed but will become part of normal systems as a back up to confirm existing data.

Oh well feel free to carry on speeding with you phone or other gps nav device enabled in bike or car, you'll find out next time you come to grief the facts about that evidence recorder your carrying around...

[bogan]

close enough...
GPS will record close enough...
...close enough
... the difference is negligible...

Nope, still not sounding like a gold standard

So people that break the law will all be put off breaking another one to cover their arse, just cos it would be breaking a law? not too solid logic there bud. The point is that it won't become a gold-standard speed measurement precisely because it is so easy to tamper with. Neither is it a reading to be relied upon unless you have to submit evidence of 300 other offenses to get off just the one.

Ah, so it isn't a way to get off tickets anymore, just a conspiracy theory way to get more? Doesn't seem like something to promote over radar or speedo then does it

There's also a handful of fringe effects associated with GPS that can lead to inaccuracies.

Another thunderous shitlord who after losing an argument tries to find some semantics to hide behind.

The answer we were looking for by the way, is GPS doppler shift velocity calculation, go read up on that if the words aren't too big for you.

Another sore loser... no further verbal diaroeha will be entered into over this issue.

Another delusional twat who has to devolve into blanket claims of being 'right' instead of having the wherewithal to show it.

the camouflage is only to reduce the risk of Australian IS fighters from destroying the camera and making those bits of road more dangerous for the infidels who ride on them.

I hope they threw the camera down the hill, pointed it backwards or painted it bright orange.

Doesn't really matter what the intent. When you go army surplus you have to expect people to react as threatened. From the thumb nail I assumed you were implying they had radar guided SMG.

You just know if this was West Auckland that camera rig would be converted to some sort of possum hunting device by sundown.

I'd say we prob have, they do it with trucks and the southern cops did it with boy racers blowing stop signs... Anything is legit under the new SSA...
