LIDAR

Hi everybody. I got a speeding ticket. I think LIDAR measurement was affected by the fact that I had xenon flasher (tow truck) near me when I was zapped. LIDARs work at 905nm, Xenon lamps cover very wide spectrum uncluding IR. My question to everybody: how to present it in court so it (A) sounds believable and (B) sounds understandable. I lost clerk-magistrate hearing because police officer could not tell the difference between beam width and wavelength and magistrate just did not seem to care. Ideas? Opinions? Clues? Thank you! P.S.: no I do not need "don't speed" advice. We all know that most of the speeding tickets are written for nothing but revenue enhancement.

No, it wasn't.

Can't be done.

No one who could understand it would agree with it. Instead of trolling for information, learn how the system works, how the laser is modulated, how the laser is detected after striking the object in question, etc. Then you'll see how there is no way that a tow truck's light would affect the laser.

I don't think I'd care either were I the judge.

Pay the ticket. Slow down.

Apparently you have none...

Yea, sure... You're just pissed because you got caught.

I like how you didn't clain in your post that you were not speeding, at least you are honest about that bit.

Build a scale model of the site, radar it with and without the Xenon flasher. First test it with video, and submit transcripts with drawings.

Threaten (motion) the court with live demonstrations, (subpoena) with the police officer and the radar manufacturer as witness.

By the way, I am not a lawyer. But I just won $500 from Walmart, since Sam Walton did not show up in court.

Where do people like you come from? What, are you proud that someone got a speeding ticket? The OP is absolutely right, the vast majority of all traffic enforcement tickets are to make money for the city, i.e. red light cameras that bill you $450 when you turn right on red without stopping. How could you not feel stupid for falling for it and cheering for city hall? Did mommy and daddy always treat you to obey the rules and now you can't think for yourself? ITS A SCAM.

"proud that someone got a speeding ticket?" ????? Where could this have possibly come from?

There's no point in getting a speeding ticket. Nothing is so critical that I need to be there about four seconds sooner. I get a kick out of watching the leadfoots jackrabbit away on green, while I make a nice gentle leisurely departure, and watch their brake lights come up about half-way to the stop light, while I gently coast to the light, and gently drift alongside him, virtually coasting to a stop. I usually give them a big smile and thumbs-up, just to piss'em off. >:->

I'm proud of not throwing dollars out my tailpipe, yes. ;-)

But about tickets - it is much, much cheaper and less inconvenient if you just don't bother to get the ticket in the first place.

But I guess you kids will need a couple more decades or so in the School of Hard Knocks, if you're ever going to learn anything at all.

Good Luck! Rich

Are you proud to be an extortionist?

No, just asserting my consumer right. Sam's associate messed up my tire stubs with power tools. OK, I messed up the axle and rotor when replacing them. But I did not charge them for the parts, just the labors. Sam's manger did not listen to me either.

Its typically a 905 nanometer pulsed laser, a few nanoseconds wide, multiple tens of shots per second so it "tracks" you as you fly towards it, giving it a huge averaging time. Once the first few shots fires it "range gates" so it only sees its own light. Xenon lights up at 2-3 shots a second with 200 uSec or more long pulses, with only a little of its light at 905 to fit into the 905 nm bandpass filter in front of the detector. Ie the xenon when fired is steady state background to the lidar. . Since its set up to be eyesafe the beam is expanded and thus has almost zero divergence. Since the spot size of the scattered light is small compared to the target, the collection optics are boresighted to the laser and have a tight limiting arpeture, thus they wont see much of the strobe.

Even if you could find a sympathetic judge, you don't stand a chance from a engineering point of view. All this was covered in the test court case used to win approval of the laser method. If you were the judge, would you take the heat for loosing the local state entity its source of discretionary funds that it can spend on whatever it wants without legislative fiat? Pay the %$#@ tax, get on with your life. Next Time, In Court, I would ask the officer to prove it was in current calibration and traceable to a standard, That, they probably cannot do, and you may get off on that one.

Photo radar went all the way to the Ohio State Supreme Court as a civil penalty , not a traffic offense, and was sustained. It may go higher. The opponents of photo radar had the Fraternal Order of Police and the Insurance Companies, of all groups, on their side!

Gasoline engines are most efficient near full throttle, at a speed just below the torque peak.

In other words, unless they let the revs climb too high, they're using less gas than you--at least until the point where they hit the brake pedal. That's where the inefficiency is--wasting the energy heating the brakes. If they judged it better and coasted to a stop too, they'd use less gas *and* have a better time.

"sloths" often cause traffic clogs; they are the "hairballs in the throat of traffic".

by "speeding"(an arbitrary limit set by politics),I often pass thru lights on the green instead of getting stuck at every light. Traffic also flows faster,so more vehicles pass per hour. (important for overcapacity roads,like much of Orlando) People do get to their destinations faster,because they didn't stop for 2 minutes at each light.

I also manage to get myself in the open gaps -between- traffic clumps(caused by the sloths and clueless),a much safer position.

Where appropriate *for traffic/roadway conditions* at that moment,I either travel over or under the speed limit,as I desire. (and no different than local police,too)

I stop for red lights,I signal for lane changes and turns,more than many drivers do these days.I merge ASAP instead of being a last-minute lane changer.I "look ahead,think ahead,and act ahead". I do NOT use my cellphone while driving,ALL my attention is on driving.

IMO,in Orlando's heavy traffic,where speeding is at all possible,it's not any factor in safe driving.

If you are talking about the "studs" that are attached to the rotor, their mechanics did same thing to our minivan and left only three lug nuts holding on the tires on each of the front sides. They did sort of mention it, (as if it were an existing condition) real baffoons! We needed brake work anyway so I had a reputable brake shop replace the studs. I hope you can collect on your claim. Winning the case is only the start of the battle.

That looks like it's pretty well covered. I was thinking the OP might hire a really smart lawyer, perhaps a patent attorney, to make up all sorts of claims along the lines the OP was trying to make. They probably charge $450 per hour, and this would take maybe three or four hours of the attorney's time. That sounds expensive, but it could be worth it to the OP if he has 14 points on his driver's record and the speeding conviction would push him up to the 15 points where he would lose his license for a year.

But if he's sure to lose the case, that's a lot of money to spend for nothing.

Yes, they stripped three out of four studs. Probably too lazy to hand thread it, just power jam it in.

But you don't need to remove the axle nut for brake work. After breaking the torque wrench, I had to grind out part of the axle and nut with several titanium bit stems. The bits did not last more than a few seconds, but the stems grind out the harden nut and axle slowly. I eventually got it out, after ruining the drill as well.

The axle nut is not supposed to be reused. So, the $10 nut, $10 cap and $3 pins are parts added to the $40 stubs. I am not including the axle and rotor, since a good mechanic would not have damaged them. But a good mechanic would not have damaged the stubs in the first place. A simple tire replacement ends up with axle, rotor and ball joint replacements.

In the case of bad mechanic vs. bad mechanic, the defendant did not show up. The bad mechanic and non-lawyer plaintiff did not file the proof of service properly. The court ordered to reschedule the case. Plaintiff offered to drop the case.

Oh yes, the defendant mailed a check a week before the court date.

In my younger days, I owned a 1970 Plymouth Barracuda (w/440 & Dana rear) and the wheel lug nuts on the driver's side had reversed threads. Poor technician was out there for 30 minutes trying to get the wheels off with an air impact wrench!! He finally came in and apologized that he just couldn't help me because he couldn't get the tires off....!!

That car went through a lot of tires BTW :)

As to the LIDAR issue, if it's worth your time, you can always contest the ticket. Here, they make if difficult by turning in into a 2, 3, or even 4-step process. I guess they figure if you miss enough work, they'll prevail. That said, the deal gets sweeter the later in the process you go.

I had a U-Turn violation a couple years back and went through this hassle. Started out as a ~$125 infraction, then down to $50 + points (at a pre-trial Judge's discretion), then just a fine (again, pre- trial). I went all the way and won because I was able to point out that where I made my illegal U-Turn was actually MUCH safer than the first permissible point at which to make the turn (nearly a half-mile away). The Judge agreed!, and ordered the County engineers to investigate the signage! (I was lucky, I guess?)

Still, it is my understanding if the officer does not show up in court, you win by default. So, I guess that's always worth a try. All that said, it is often the right approach to just pay the ticket.

Not withstanding the fact that you are *REQUIRED* to stop before turning right? What happened to just following the rules?

It? What it?

Either follow the rules or change the rules or pay the price. Easy concept.

Objection your honor. Unsubstantiated speculation. Move to strike.

I don't know what happened. But I am sure it was inexperienced technician with impact wrench, and "more power, said Jim". The Summon and Compliant got to their regional manager and perhaps higher. I hope they would review their procedures, rules, policies and trainings. It might save their future customers. But again, they might just pay it off after the fact, once in a while.

Sort of like Providence. Apparently we now have traffic worse than that in Boston.
