I've recently been noticing lots of police cars parked in the middle divider of the highway or along the sides trying to catch people speeding, especially on the M1 to and from Geelong.
My question is, do they have radars in their cars that register your speed and automatically issue tickets or do they need to chase you down to give you your ticket?

that would turn a ticket into jail time :)
The OP is asking because he/she has already sped past one and is now wondering if a fine will be issued given that there was no chase.
@kahn: I was going 110 in 100 zone, shat myself when I saw them
@lurker69: It’s more likely that your speedo said 110km/h, but your actual speed is 105km/h. After they give you the 3km/h allowance on your ticket, that makes your infringement speed 102km… and that’s just not worth the cops time to chase you down for and potentially miss catching someone doing 120km/h.
But, let it be a wake up call. Next time, the copper may just need fines to fill a quota and, well, 2km over is over…
@lurker69: You want to control your bowels or you'll get done for "farting with intent" like that bloke in Austria.

You should be looking for a car cleaning deal
All depends on what they ate for breakfast that day
ANPR is more likely.
I guess you mean they are scanning number plates on the way past looking for wanted/unregistered etc vehicles, rather than a speed trap?
Only one way to find out
I was under the impression they couldn't send it
They need to pull you over and give you a fine.
This. Confirmed by a HP mate.
Also, if you use GPS to confirm your speed and set to 107 in a 100 you won't get done.
What is on your speedo vs GPS will depend on the vehicle. Some can be out by up to 10km/h at 100, others might be less.
You misunderstood me, I almost always use the GPS speed everywhere and haven't been done in several years. Speedo is always lower so I revert to that when not using Waze. Which also has the advantage of pointing out speed cameras.
No. I didn’t misunderstand. You are suggesting that everyone should set their speedo to 107 to get to 100 which could wind up with them driving at anywhere between about 98 and 100 spending on the vehicle.
Pretty bad advice given your GPS speed is unreliable and will also not be usable if you tried to fight a ticket
why Is the GPS speed unreliable? IMO it’s more accurate than the dial on the dash as it measures your position in real time. Sure, it’s only accurate to a few metres, but the sample rate and calculations averaging your speed make it quite accurate and getting better with each generation of receiver.
The speedo relies on the tyre diameter, which changes a fair bit, then the accuracy of the gauge needs to be no better than X+10% and typically reads higher than actual.
Do agree though, that setting your speed to be right on the limit leaves no room for error such as overrun down a hill.
GPS are pretty accurate, but it all depends on where is it used. We have a pretty expensive unit for testing truck setups at work and I think it has a sample rate of 10Hz (or maybe more), but there is still a big list of where and how you can use it. No corners, no inclines or declines, no buildings/built up area, no overhanging trees, no overcast skies… etc.
While a GPS is more accurate out of the box, a car, bike or truck speedo can be made to be just as accurate and both have their pros and cons.
I usually just test a car once with my GPS and work out how far out it is at 60, 80 and 100, and just adjust from there. But for @Mechz to suggest you wont get done for 107km/h in a 100km/h zone is just outright wrong. All you need is a cop on a quota or a bent out of shape road Nazi, and they will ping people for 104~107 in a 100…

Now I see that, I may have mistaken the meaning by Mechz. While I used to set my speed up to 10 over he limit, it isn’t worth it now. As you say, all it takes is a bored copper to make your day miserable all in the attempt to save a few minutes.
my car is out by about 5km/h, my partners car by about 2km/h and her parents cars is actually spot on as far as GPS is concerned.
brand, tyres, age etc it all comes into play.Pity the road side speed boards they use that show your speed are not always accurate,
would be good if they were, could get a good understanding of speedo and GPS variances.In Victoria, cop cars do not act as speed cameras.
The new speed cameras launched in the last few months now photograph you approaching out the tinted rear window of an SUV, so you can get your speeding ticket without needing to replace your underpants.
Are you planning on speeding away?
