A Day in court...

Of course not top gear you clown, 2nd IIRC.

I tried to race a bus at a set of lights in my vw beetle once. it won.
a semi passed me going up the tom ugly bridge once as well.

Getting 1500w out of a 200w motor would involve some interesting tweeks (ie
multiplying the voltage by 8), and I suspect not last very long.]

 

So that's how it works! Hmmmm... so if I swap the 12V electrics in my car
with a 24V system, will that double the 250Kw to 500Kw? Why doesn't the
manufacturer offer this as a factory option?

and what gear was the OP in at the time of his offence?

Because the necessary energy polarisers always seem to be out of stock ...

 

No.

But if you run the alternator voltage sensing line to a resistor bridge
instead of the battery +, you can get 24V from your alternator and
pretty much double the electrical output available for your lights. Of
course lots of other things are going to want conversion to cope with 24
volts too. It's more practical with an older car or motorcycle.

Because 12V is enough and is standard. But they are going to 42V (3 x
12V, which is really 14V) in the next few years for much the same reason.


See what happens if you ask a facetious question around here - some
bastard takes you seriously!

 

the reason for that is more to do with higher current draws today with power
everything which means bigger
cables and more weight

solution is to up volatges and reduce current

remember a couple of years ago that BMW's 7 series was runing 2 x
alternators which were also
water cooled to handle the loads

 

So were you the only vehicle in view when he pinged you?

You need to find out if their operating procedures require you to be the
only vehicle in view, particularly if, as a motorcyclist, you had a car
right behind you. Ideally NOT one you've just claimed on oath that
you've just overtaken and which is therefore travelling slower than you
are...

Make sure you tell the judge this. Then he'll figure if you weren't
guilty the first time, he'll let the fine stand anyway since you just
aid you DID speed next time.

They're not actually required to show it to you, and even if they did,
it would prove very little, since it doesn't show how long ago the
reading was taken or what the unit was pointed at.

Hilly and windy suggests they may well have got you alone.
Just overtaken strongly suggests you had been accelerating and that your
attention would have been on the road ahead, not the speedo. Face it,
there's every chance you were over. You yourself say you don't believe
you were doing more than low 60s...

Plausible, except that the cop will swear otherwise and the court will
believe him ahead of you. And it's just as plausible that you did get up
to more than 10kph over the 50kph limit. In a 50 zone, 61kph or 73kph
doesn't matter, (in Victoria) it's the same offence and the same fine.

If you decision is based on money then you are daft even arguing. It
will only get more expensive.

 

That is the best advice i have read on the subject. Go with your strongest
argument and stick to it. keep it simple.

Which is why they changed from six to twelve volts (well.. everybody except
VW).

Mercedes was running dual 70 amp alternators in 68 on the 600 limo. Don't
think they were watercooled though.

this is the way I'll go, a motorcyclist got off this way ealier in the year
here in Vic, anyone have a link, it made the news.

he prove that speding was the only safe way to overtake the car, he only got
pinged got a few Kms over, wouldnt work for high speeds

Marty

 

All very good advice, particularly the 'Your Worship' bit. Given
the inordinate number of petty criminals who seem to spend all their
free time watching Amercian television calling the Magistrate 'Your
Honour', calling her by her correct title might well put her in a
good enough mood to give you the benefit of the doubt right there.

A car was directly in front of me and turned off. If the radar was pointed
at the car then me, surely it would have an incorrect reading?

"I tested it on a similarly inclined road that ws zoned 70"

Oh I reckon I was doing about 60 and will cop that.

In NSW it's different.

I'm prepared to lose a little bit of money for the experience. I don't want
it to turn into thousands of dollars however.

 

What ADR is that one please ?

No, assuming for argument's sake you didn't blow the crap out of everything,
you would quadruple the power.

In a linear system, when you double the voltage through the same resistance,
you double the current. Power is a measure of Voltage multipled by Current,
so the Power is quadrupled.

12 Volts into 12 Ohms gives 1 Amp, or 12 Watts.

24 Volts into 12 Ohms gives 2 Amps or 48 Watts.

Electric motors vary that a little, because they have impedance as well as
resistance and are therefore not linear.

But, playing the game a little, in your 250 kw 12V car the current would be
20,833.33 Amps (Must be humungous cables...) at 576 milli Ohms (0.000576
Ohms)

Doubling your Voltage to 24 Volts gives 41,666 Amps (definitely need bigger
cables now) and a cool 1 MW!

Find out the Manufacturer of the Radar,

Then see if you can get a copy of the manufacturer's guidelines and then get
a copy of the Police Guidelines (Freedom in information act). one of the
guidelines above will state about error due to hills, metallic objects
behind you etc.

I saw a story on ACA ages ago about a guy who got off by geting a copy of
the guidelines and it showed that the cops shouldn't have been using the
radar in that location.

 

I think it's important to note this case was heard in a country courtroom...
and he was represented by a barrister.

I reckon my best chance is to argue that the location of the radar is
outside guidelines. It is a reasonable incline, there isn't a straight piece
on the road longer than perhaps 150m (? Not sure exactly but the road snakes
up the hill with barely no straight bits), and being suburban there's lots
of cars parked on either side. The little I know about radar suggests this
case is a bit dodgy, but I'd like an expert opinion if poss without paying
through the nose for it.
