It must be safe to speed..
Discussion
..where there are no cameras!
Logically this means;-
* outside schools
* hospitals
* very busy motorways
* any busy road
* on roads with lots of twisty bits & ditches
And for camera vans, or BiB with a pro-laser
* rainy/snowy or foggy days
Any more? seems to me that if there are no cams, then it must have been decided it's perfectly ok to speed. Can't be right, but seems to be true.

From a different angle the recent advert from Speed Angel advertising their product as an aid to road users to identify black spots, all a bit tongue in cheek.
Lets face it speed cameras are well out of date technology that either need updating or getting scrapped until something better comes along or at least put them outside schools.

The irony if this is true
Only in the most dagerous conditions do "safety" vans fail to work properly.
Pretty sure it's true.
And yes, the irony. Although the last time I was going fast in the pissing down rain or fog was never.

I hope I'm interpreting that correctly, in which case:
Good! Actually if there's not too much traffic about a bit of good progress in the wet can be fun. The XJ12 used to put up so much spray it looked like power boat racing.
Best wishes all,
Dave.
I was caught by North Wales Police by laser and the officer on his statement clearly said "It was RAINING" putting it in capitals like that. I went to court for it.
It's totally academic now but do you think there might have been a case to argue that rain can introduce inaccuracies into the LTI20/20 reading? I did some research on it at the time but could find nothing.

ironic ain't it Dave? night time in the rain is the best time to avoid a nicking from forward facing laser. Or any laser for that matter. Or indeed any camera... eg, fog impairs photos & doppler.
Ironic it certainly is Carl. Fog is a different matter of course, but visibility can often be quite satisfactory in the wet. It all depends...
Best wishes all,
Dave.
The situation seems to be that the best time to go out on enforcement is when it is least necessary. High visibility dry conditions when the average motorist will be driving to the conditions as they see them (good). If enforcement was carried out in terrible conditions where idiots were driving inappropriately for the conditions then i would be less hostile towards speed enforcement. The number of times i've been driving at 40-50mph on the motorway in appalling conditions (fog, spray, high winds etc) and some twat has gone past doing the speed he always does (80-100mph). As far as enforcement is concerned he is less likely to be caught than me doing (80-100mph) in dry clear conditions!
Of course the tool doing 90mph in driving rain if he is caught by a BiB will hopefully get dealt with more harshly than someone doing 90mph at 6am on a dry summer morning.

I have known conditions where 40 mph on a motorway was plenty fast enough by my reckoning. It was one afternoon a few months ago on the M180, extremely heavy rain and enough spray to make visibility very bad, so I settled to 40 mph in lane 1 and far enough back from an HGV so I just kept him in sight. I was worried about being hit from behind, so it was not a comfortable situation, but the best I could do at the time.
On the other hand I have quite recently driven at 90 mph on dual carriageways and motorways during moderate rain, but you need the visibility to be good and you need plenty of space around you. If there is any doubt about those requirements being maintained, then I agree it would be extremely foolish to do it.
A lot of the situations we discuss here are dependent on an accurate assessment of the conditions, and then ensuring that the driving is appropriate. It can take quite a while to establish those abilities to a reliable level, but that is what we need to aim for.
Best wishes all,
Dave.
Strange that some think that a laser is accurate in good conditions. Lasers are not designed for use on moving targets. Distance measurement yes, firing at any moving object and expecting proper 100% accuracy, no I don't think so. And as for rain, any suspended particle in the lasers line will have some effect. I would include polen in high enough consentration, maybe even trafic fumes on a busy motorway who knows.

LTI 2020 is pretty good at rejecting errors.
44 flashes. 30 of the reflections need to have the same pulse height/width rise/fall time. Plus all 30 need to have the same (within a tight margin) dv/dt characterstics.
Rain drops caused preferential reflections which, if there are enough, cause too much reflective noise.
in other words it reduces the range but NOT the accuracy.
