Question about Laser (Lidar) speed detection

OK. Here's the thing. I am NOT a speed-demon, so please do not lecture unless you absolutely cannot stop yourself.

I am considering some out-of-state trips on the new Wing, and I am considering a radar detector. I am inclined towards the escort 9500i. HOWEVER, iam curoius about the newer laser detection.

NOT how it works, that I pretty much comprehend. Nor, am I interested in Jamming. What I am curious about is this:
What percentage of speed dection does it comprise? How fast is it being adopted across the country? I have googled just a tad, but did not see this type of info.

What I'm trying to determine is NOT whether or not I will get stopped (I REALLY don't speed that much) but how long a new dectector will be viable (for plain old radar in all the various bands).

While I don't zip along at 75 or 80 MPH, I do sometimes pass a car, or two or 3 that are in the right lane, going a bit slower than me. We are all exceeding the posted limit, but not by a huge amount. However, when I pass, I believe in getting it the heck over with. I don't like riding down the road with a car right beside me for any period of time. I want to be either well back, or ahead enough that I am seen.

So, when I pass, there are times when I am in the left, accelerating, feeling vulnerable, and will soon merge right and slow back down. But, for those moments, it would be nice to have some warning if there's somebody ahead "Lighting Up" cars as they go by. I know it's not fool-proof. But it sure could improve the odds for this manuever, and for that alone, I like the idea. The same applies on my commute to work, which is over 40 miles. Car or Bike, I don't like to take "minutes" to "ease by" somebody. But, if I am going to shell out some $$$, then I am curious about how fast the newer detection technologies are being adopted, and how soon the gizmo will be half-way (or more ) useless.

So, if anybody can point me to a web-site that talks about the adoption and/or prevalence of Lidar, and newer technolgies, I would like to read it. I figure somebody out there is in the know about these things, and all I need is a link or two.

Thanks, (This Forum is WONDERFUL in many ways...! Very active and very useful...!)

I've had my 9500i on the bike for about 14,000 miles now.
I think it's one of the best accessories I own.

Thousands (maybe ten's of thousands?) of radar alerts in the past year riding throughout the SE of the USA.

lots of X band alerts (99% false alerts)
lots of K band alerts (75% false alerts)
many Ka band alerts (95% the "real" thing)

less than 5 total (five) laser alerts during that whole time.
(not five percent, less than FIVE total lasar "hits")
... bottom line: not used much in the SouthEast U.S.

Re: Question about Laser (Lidar) speed detection

Laser is a thin beam of light, usually aimed at a car's license plate or other "reflective" surface. The narrowness of the beam makes it easier for the LEO to single out/sight in a vehicle, but it also precludes the detection of the threat. Because the sensor is looking optically and there is little bleedover, conventional understanding is that "if you hear a laser alert, it's already too late because YOU were the target". You will rarely, if ever, get an alert when someone else (even directly in front or beside you) gets hit.

That being said, all my laser alerts have always been false -- Lexus Navigation screens will set it off if too close...

Re: Question about Laser (Lidar) speed detection

I have owned the escort 8500 for 3.5 years and have had Laser detected exactly once here in NC. On that occasion I saw the County Mountie standing outside of his patrol car with another observer like they were experimenting with this new toy. Maybe it was on loan to the sheriff's office or maybe the escort doesn't detect laser very well.

Re: Question about Laser (Lidar) speed detection

I believe that if a lazer tags you, you have been had. It is so narrow that very few "detectors" will help any. I made a radar "tester" out of an old in house burglar alarm. It consists of a 10 gHz oscillator that is powered by a 9 volt battery. I carry it on long trips and have a ball "testing" folks radar detectors for them on the interstate as they move along. Im of the belief that most warnings are from external sources, such as my home made tester, and things other than police radar.
From what you said about how you drive, youre not gonna get a ticket for speeding. I believe that the police look for people doing dumb stuff like weaving in and out of lanes, blantent speeding and agressive driving. In a few states, radar detectors are illegal.

Re: Question about Laser (Lidar) speed detection

I run the Escort Passport 8500 X50 (Blue).

In California the CHP (California Highway Patrol) is increasing is usage of LIDAR as are many city Police departments.

LIDAR can only be used from a stationary position, not while in a moving vehicle. As stated earlier if your laser detector goes off while you are out riding and you are speeding , you have already received a ticket, you just need to pull over so the nice Officer can hand it to you!

I still find some comfort in the laser alarm going off and I'm not speeding just knowing That I was just zapped. While riding in a group I may jump on the HAM or CB radio and send out a "Heads Up". My only speeding ticket in recent history was on my Wing carving some canyon roads and really enjoying myself when the friendly CHP standing at the side of the road waves me over to receive my "Having way too much fun" ticket. The laser detector never went off for that one... laser hits are still pretty rare, but there are certain areas around here that use them quite bit. I have yet to receive a Laser Alert that I know saved me a ticket. The number of laser Alerts I have received are probably fewer than 5 in the last 2-3 years and i was not exceeding the posted speed limit enough to warrant a ticket. It does however reinforce in my Mind the areas where Laser Speed Enforcement is occurring and perhaps i should pay even closer attention to my driving habits.

If your are buying radar/laser detector based solely on its "Laser" capabilities, then no it is not worth it. BUT, A RD like the 8500 or 9500 from Escort is worth the price of admission because of its superior performance in all bands that it works on. With the 9500 and its GPS driven false alert eliminator capability is a really nice feature.

I'm personally thinking of turning my "X" band detection off all together on my 8500. 100% false alerts on X-band as near as I can tell. Ka-Band on the other hand is nearly 100% accurate on true alerts.

The "Few" states being Virginia and Washington D.C.

They are not legal at all for commercial truck drivers to use.

Re: Question about Laser (Lidar) speed detection

Don't know about any website showing adoption rates for LIDAR.

But when we got our detector (STi Driver) and used it on our first trip (car) we had two Laser hits. First one in NY and the second one in St. Louis. Since then we haven't had any encounters. Just two false alarms.

As stated before. There is no warning period. When it goes off you have been clocked by the officer and only get visual and vocal confirmation by the detector.

Since it only can be used in a stopped vehicle there are not that many in use today. However rest assured that everyone is working hard to eliminate that "fault". Once resolved it's going to be the "standard" for all police speed enforcement.

I spend a lot of time running up and down the Eastern seaboard all the way to Flori duh and out to say, Idaho, Montana, the Dakotas...LIDAR is a non-issue. I think the <has to be stationary> thing pretty much kills it as LEOs like to be moving. Once he parks and is spotted, the word gets out on his location and he is done.

In small towns it may be different, but I spend my time on the interstates...BTW, why not consider jamming? Expensive but supposed to be da bomb for stealth ninja running...

I doubt that LiDAR will have a moving mode anytime soon, if ever. The major advangtage to LiDAR is also the major feature limiting its usefullness in a moving mode. It has to be aimed at the vehicle you want to clock. Not very easy or safe to do while also driving.

Re: Question about Laser (Lidar) speed detection

Radar detectors have attempted to be made illegal in DC, Virginia, and Connecticut I think. Their legislatures are trying to say that a passive radio receiver can be illegal to own. If our esteemed Supremes would *ever* get off their butts and rule in this, I'm sure the nazi states will be forced to accept reality.
