Laser protection

Isn't it funny how it is more difficult to detect speeders in heavy traffic and so easy when there is little traffic? Going much faster (or slower for that matter) than the surrounding vehicles in congested traffic is dangerous and stupid, yet violaters often get away with it. Police are rarely there when they could do the most good. Just being visible would increase safety.

On the other hand, going a bit over the posted speed limit when traffic is very light or non-existant is not very dangerous on limited access roads, yet that is usually when and where the police are visible.

Define "A bit".
In most places I've been during my past 45 years of driving (anything) going "a bit" over the limit has never resulted in a ticket, a warning or two with no points or fine but Never a ticket. Now for me "a bit" means 10 MPH or less and I doubt many LEOÔÇÖs bother with folks going ÔÇ£a bitÔÇØ over. Now, 10 or more over can get you an invite, 20 can get you in serious trouble, thou mostly they will knock it down to under 20 so there is no reckless charge if you are polite and are not being an ass about it or the manner in which you were operating the vehicle.

As for radar/laser avoidance, don't be stupid about speed and if you do, then pay up, you Were in violation, period.

'Protect you from laser'? Now there's an interesting concept...I agree with the folks who counsel that the only 'protection' from a speeding ticket is to slow the heck down! A jamming device will most likely be illegal, perhaps even a felony to use or possess, not sure what the current laws state...And it's foolish to deny that any sort of ladar/radar/laser/whatever device is wanted other than to facilitate speeding!

Hey, just how many electronic devices do we want on our motorcycles in the quest to slow down and relax?

SShhhh, no one is supposed to know that.....

You cannot jam a laser signal except by EMI, which would probably kill your bike too. The only counter attack to laser mapping is to send your own laser signal back to the source. This involves spotting the laser, targeting the source, and sending your own signal back to the source. Naturally, your signal will say you are going slower than your actual speed. There is no commercial laser jammer doing this and it would need a 360 degree rotating lens to do it. The only way the military can "jam" lasers is with smoke. Who knew my old Triumph was really jamming police lasers from the rear? No wonder I never got any tickets on that bike!

That's what laser shifters do. They are transceivers. It's pretty basic ECM. Lots of videos about this: Shifters

Thanks for the tip!! :lol

Just made a fortune off my ACME DEER WHISTLE stock.

Just because you believe that lidar speed detection equipment from the past few years is snake oil doesn't make it so. Lidar shifters are now illegal in something like 10 states for a good reason. They work.

From a purely technical perspective, I'm a military electronic tech, trained in radar and ECM to the component level. I've also been repairing electronic equipment for a living for over 40 years. Laser frequency shifters are perfectly capable of confusing speed sensing lidar if they are installed correctly and if the speed lidar beam actually hits the antenna. This is electronic countermeasures 101 and it goes back to the 1940's.

Have you ever noticed that many of the same companies that make the police equipment make the civilian equipment? Just like the phone company makes money off caller ID and call blocking.

I don't doubt a word you say, and your qualifications are, to say the least, impressive.

But I too have "been in the business for 32+years" and I ran out of tickets before I ran out of targets - many of whom trusted their fate to 'detectors, jammers. etc.'

Whether the sophisticated devices we LEO's used, or the Electronic Countermeasures employed by the speedy, there is a human factor in all of it - perhaps that's what levels the playing field from time to time.

Safe Riding This Summer up there in MA. :thumb
 
Anything built can be jammed. All you need is a stronger signal than the one reflected from your vehicle. The problem is that it takes a license to operate on the various frequencies we are talking about because the effective jamming devices are all transmitters. Just pay the ticket or slow down and travel without all the stress.
 
Wait a minute, how can a laser shifter work if it does not fix the location of the police laser and send a signal back to it? Is there no directional requirement for the laser signal you are emitting from the car to the cop? Is there some sort of 360 degree laser emitter you can send from your car?
 
sorry but I couldn't resist...

Why can't you build whatever beam pattern you want? The usual configuration seems to be two devices in the front and one in the rear connected to a controller.
 
Escort makes a Laser shifter but I do not think that you could fit it on a motor cycle. I have one on my Lexus RX450H and it works very well. Here in Colorado we have some communities that are tightening the over and under limits to 2 or 3 MPH. This is just a revenue grab.
 
Keep in mind that most police officers who are Radar/Laser certified are also regarded as experts in visual speed estimation and use Radar/Lidar as a secondary confirmation. So if you are zipping along at some ungodly speed with your radar jammer/laser deflector/space-time continuum shifter running, it's still possible to be cited and convicted based only on the officer's observation.

And yes, I agree that the Dr. Evil post is the best of this questionable topic. :D
 
I've heard it said that tin foil hats offer good protection from Lasers as well as cosmic rays and from having ideas stollen from your brain....

just saying... :laugh
