Fair, I'll elaborate on the reasoning of my reply.
I'm questioning just the quoted statement, not the entire message.
The first statement (above) shows Peter using a common, but largely
inaccurate and inconsistent method of gauging real speed, when it would
appear the speedo has a scale and/or non-linear error.
I've only met a few vehicles that were close enough for me to consider
good enough, all the others were nothing other than just hopeless. So,
I *NEVER* consider a built-in speedo as useful, even if I have enough
experience with accurate comparisons to do it.
Had he said, "my GPS thingamybobba said 82Km/h as I passed the 80 zone
camera at a steady speed..." we wouldn't be having this argument.
It gets a bit more complex though, although GPS is reasonably accurate
(OK, very) it's only good at showing you your instantaneous speed, the
update is quite slow (1-2 seconds) so if your speed is varying, it's not
going to be of help.
Your built-in speedo has a high update rate, but its accuracy may
waver. If the scale and/or linearity error isn't too bad (I've had
bikes that were next to useless) I only trust GPS, and guess any quick
relative changes, otherwise, I use a combination of the two.
We're not talking about that though, this is a mere guess said vehicle
would be need to be *reading* 98Km/h to explain the reported 91Km/h
fine. Based on assumed speed measuring equipment leeway and offset of
That's not going to cut it, and certainly no-one of relevant authority
else is going to take that explanation either.

I have discovered similar things since I just got a very cheap gps,$60
it has software in it which tells you the limit of the road you are on,
warns if you exceed it,warns of cameras, school zones, 40 in school
hours, normal limit non school hours etc.(extra one off $ 9.90 for the
speed alert software.)

and you had your number plate on an angle to fool the camera!

no, the people run the server/webpage/forum have full control over
