How's this police radar thing work?

I'm driving down the road, in what I later saw was a 30 zone, probably speeding on a long and gradual downhill with a car tailgating me and a cop jumps out from behind some bushes lining a school's driveway and flags down the car behind me. I saw his scooter in the driveway as I looked back.


Can they tell the speed of individual cars that are close together?

Yes, laser can be honed in like a gun scope on a specific target. It can only be used when the officer is parked however, which it sounds like he was.

Edit: heres a picture you can see the scope that they can target right on any object.

And add to that laser detectors are basically useless. The system is pinpoint accurate so by the time you're alerted, you're already tagged.

First off, a cop shouldn't/doesn't use a radar gun to pick the faster speeder or speeder.. He uses his common sense to see who's speeding, then once he sees someone going faster than they should he uses lidar most likely, there's a dot in optic shows you the speed of target but if Their close together it shows the fastest moving target

So if you and another guy were close but you flying up on him, it will hone on your speed. Yep yep. Uses tons of angles of reflections toget your speed not just one. Most accurate on front of vehicle but can be done from angles. Not sideways, because its not moving closer or farther from you to send:receive the signals.

I'm lidar certified so yeah. I've had to explain it in court and its easier in words than typing. I'm on iPhone and hurrying explanation. Moving lidar does same thing (use it incars while moving) show your speed and there's and does algorithm to do the math to pin point the speed. Can't fight them honestly if your pegged and you fight it and cop shows up and he is certified and machines current on annual calibration by state your ticket is almost surely yours unless you have a forgiving judge and possibly first time

Or unless he writes the wrong date on the ticket like the cop did on mine.

Huge pet peeve to me is spelling of streets and info. He's right they do get tossed over that.

Laser's move so slowly though.

Speed of light is like so 20th century.

And it's the number one cause of climate change.

Same deal pisses me off when people slam on their brakes when they see a cop on the freeway. Seriously...if he was going to pull you over for 8 over...you'd be toast already. There is no reason to slow down to 3-4 under the speed limit people!!!

Seriously. I hate that. I pass cops all the time. My buddy is a cop in Austin and he knows someone on the force who just messes with people on the highway. He'll do 64 in a 65 and see if people have the guts to pass him. Doesn't bother me since I'll just scoot by at 65-68 and be fine.

For the heck of it OP here is a pic of what it looks like down the scope (i think)

Is the 1025 the distance in feet? That is a pretty long way...

I don't know. Found it on a google search. Maybe legion could tell us.

yep, I won't pass a cop doing 8-9 over...but I have no problem just setting the limit to ~4 over and passing them. My tint is not legal in all the surrounding states so if I am out of state it gets a little more ballsy though as they like to mess with people that take pride in their car.
