radar detectors

[spudchucka]

Yeah, read it. Now tell me if the car, a moving object, gives an error reading or inaccurate speed like the stationary object.

Here's the Stalker Laser spec sheet from their web site. Make your own mind up about error readings.

Dropped down the Tauranga side of the Kaimais tonight in my car at 150+km/h in the dark and light rain. Hp car sitting on opposite side of the road without any illumination must have got me on radar cause I did'nt see him untill about 200m away.I did'nt even brake, there was no point. He/She did not chase me but I did see the brake light flash once in my mirror like it was being put into gear(Automatic)...I figured there'd be a mate up ahead waiting to pounce and sure enough I passed him/her above the limit too!
No car chase, no ticket...wassup?The rain fuck the radars?or my headlights...physics lesson please!

In heavy rain with puddles on the road the radar will sometimes have trouble picking up the patrol ground speed, if it can't get a ground speed then it won't get the target speed either. This isn't a problem if the radar is set in stationary mode. Guess you were just lucky. I have to say though, WTF were you doing traveling at 150kph+ on a dark and rainy night?

Spud - you stole your quote on your sig from Law & Order

Spud - you stole your quote on your sig from Law & Order

Actually its been floating around for ages, I just find it a bit of a giggle in this environment.

Here's some other favourites.

"The handcuffs are tight because they're new. They'll stretch out after you wear them awhile."

"Take your hands off the car, and I'll make your birth certificate a worthless document."

"Remember, when you gotta cuff 'em.... nobody is your friend."

"If you run, you'll only go to jail tired."

"That says POLICE, not taxi."

"Can you run faster than 1,200 feet per second?" (if you aren't a shooter, that is the average speed of a 9mm projectile (slug)).

"So, you don't know how fast you were going. I guess that means I can write anything I want on the ticket, huh?"

"You can't outrun a radio."

"Yes sir, you can talk to the shift supervisor, but I don't think it will help. Oh, did I mention that I am the shift supervisor?"

"Warning! You want a warning? O.K., I'm warning you not to do that again or I'll give you another ticket."

"The answer to this last question will determine whether you are drunk or not. Was Mickey Mouse a cat or dog?"

"Some people are meant to be cops, and some people are meant to call the cops."

"God made tomorrow for the crooks we don't catch today."

"Life's tough, it's tougher if you're stupid."

"Law abiding citizens sleep peacefully in their beds, solely because dedicated men and women stand ready to do violence in their behalf."

"In God we trust, all others are suspects."

"No sir, we don't have quotas anymore. We used to have quotas, but now we're allowed to write as many tickets as we want."

"I'm glad to hear the chief of police is a good, personal friend of yours. At least you know someone who can post your bail."

"We don't hire cops in this department, we hire common sense and make cops from it."

Things Not to Say to a Cop When You're Pulled Over...
I only had one officer Mr. Keg..
Back off Barney, I've got a piece.
Want to race to the station, Sparky?
I know I was weaving, but I can't find the Honeycomb Hideout!
On the way to the station let's get a twelve pack.
You'll never get those cuffs on me..!
Come on write the damn ticket, the bars close in 20 minutes!
Hey, wasn't your daughter a pork queen?
I'm surprised you stopped me, Dunkin Donuts has a 3 for 1 special!
Yeah you can see my license and registration, officer, but could you hold my beer for a minute?
Hey, you must've been doing' about 125mph (200km/h) to keep up with me! Good job!
Sorry, Officer, I didn't realize my radar detector wasn't plugged in.
I thought you had to be in relatively good physical condition to be a Police Officer.
Excuse me. Is "stick up" hyphenated?
You know, I was going to be cop, but I decided to finish high school instead.
"Bad Cop! No Donut!"
I was trying to keep up with traffic.
You're NOT gonna check the trunk, are you?
Didn't I see you get your butt kicked on "COPS" last week on TV?
I bet I could grab that gun before you finish writing my ticket
So, uh, you "on the take", or what?
Gee, officer! That's terrific. The police officer yesterday only gave me a warning too!
Do you know why you pulled me over? Good, at least one of us does.
Hey is that a 9 mm? That's nothing compared to this .44 magnum.
Aren't you one of the Village People?

Must have been your lucky day - but then again what about speed/conditions as someone mentioned? I'm not surprised you didn't brake, the cop would have had a good view of your spin-out!!
I know of Stalkers getting clear readings at 1.8km (just to add to Spudchuckas Stalker info)

[What?]

No car chase, no ticket...wassup?

They may well have been lying in wait for someone. Not unusual in this neck of the woods.

[marty]

sometimes, in light rain, the stalker can give an erroneous patrol speed, and it can add it to the target speed, but it becomes obvious pretty quickly if the cop knows he's patrolling at 90, and the patrol speed on the unit says 50. sometimes in the rain the stalker won't even pick up a speed, as the mist/water droplests dissapates the beam too much.
one of the reasons why you should ask to see the locked speed, and especially the patrol speed. it is often 'hidden', but it a simple button push to show it.

[marty]

and i have heard/used many of those quotes above. my favorites:

"That says POLICE, not taxi." (although i couldn't resist a skatie kid who said 'no sir it says poleeeze give me a ride home....)
"So, you don't know how fast you were going. I guess that means I can write anything I want on the ticket, huh?" - [I]could also be 'you didn't know you were going 90 in a 50? maybe i should give you one for dangerous[I]
"Yes sir, you can talk to the shift supervisor, but I don't think it will help. Oh, did I mention that I am the shift supervisor?"
"Warning! You want a warning? O.K., I'm warning you not to do that again or I'll give you another ticket."

and stuff that has been said to me:

You're NOT gonna check the trunk, are you? (300 cannabis plants were in there)
Sorry, Officer, I didn't realize my radar detector wasn't plugged in.
Hey, you must've been doing' about 125mph (200km/h) to keep up with me! Good job! (2 boy racers racing at 200k on tamahere straight with my marked patrol car behind them)
Gee, officer! That's terrific. The police officer yesterday only gave me a warning too! (commonly used by learner/restricted breaches)

[spudchucka]

"That says POLICE, not taxi." (although i couldn't resist a skatie kid who said 'no sir it says poleeeze give me a ride home....)

A while ago on night shift I was blue lighting to a dommy and this drunk shmuck jumped out onto the road and waved us down like there was a big emergency only to ask for a ride home. The dommy was a serious one and we were the only I car available so we had to ignore the pratt and just drive on.

[Coldkiwi]

good on ya spud, make the stupid bugger walk.

hey, you didn't mention 'good afterble consternoon!'. I understand that irritates cops on the booze patrol because they hear it so often from young smartalecs!

That one is a bit like being called a pig. You've generally heard it so many times it doesn't even register. I normally ask them if they thought that up all by themselves and compliment them on how witty they are, they usually shut up then.

Not only that, if they have been drinking they normally stuff it up!!!!

Good reply when drunk thinks patrol car is taxi? "sorry guy, we're on the way back to the station to clean the car out - the last drunk we gave a lift to spewed all over the back seat"
The normal reply when the cops won't give a drunk a lift is "ya miserable bastards, fuck you if you got into a fight, I'm not helping you" (at that stage most cops probably think "thank god for that!!)
however that reply normally has them saying "stuff that, I'm not getting in there"

Tell me with the old rules, were you had a instsnt ticket up till 50km over then it was of to court and the 50kmph was the limit for a cop car aswell (technicly, and I'm probely thinking back to MOT days) well what is the limit for cop cars now as above you tell it like you are doing 200k's with the boy's? and at what speed does a instsnt fine stop at?

[Lou Girardin]

Thanks for all the extraneous technical guff spud, but I already had it. Still doesn't answer the question though.
I'll just do some tests with a privately owned Stalker laser I know of.
The accuracy figure is interesting, John Kelly swears blind that our Stalkers are accurate to within .6 km/h. Due to 'special' software in our versions.
BTW scumdog, that must be some skilled cop that's able to hold the sight on a moving car at 1.8 km. They should send him to Iraq on a sniper team.
