Very interesting, and now you mention it - I've seen that!
A sneaky speeding crackdown.

Was chatting to some police bikers on the specifics of overtaking speed. Their response, which may of course not reflect policy, was that being on the wrong side of the road for as short a time as possible was more important than keeping to the limit at that moment.
They said if someone executed a safe 'brisk' overtake then slotted back in and dropped back to limits they would not have an issue. Obviously, 'brisk' still has certain limits mind.

A mate built a trike which used a 1275cc Leyland BMC engine on a mini front subframe at the rear - it was a really weird and clever bitsa.
As you might imagine on 10" mini wheels it accelerated quicker but revved higher and topped out at a much lower speed than it did if we put 13" morris wheels on the back.
I got it flat out approaching 100mph on Pendine Sands seeing what it could do (it blew a water hose & scalded my bloody foot is what it did :mad2
Cant tell you what that would have done to a conventional speedo reading though, as it used a front wheel speedo drive off a Honda 250.

I had a biker mate around 5-10 years ago clocked over the speed limit on an overtake. He fully admitted it, but with the help of a good lawyer got off - in court - as it was acceptable for some reason.
I don't know the detail, but have no reason to believe any of that to be incorrect.

Up to that point it sounds like a hoot!

Lancashire Constabulary Training and Development Centre at Hutton is a minute or so from where i live.
It`s an old brochure but pages 39 and 40 might interest you http://www.lancashire.police.uk/Content/UploadedImages/7356_Training_school_web.swf
The main driving school is here and the roads around here are crawling with Police doing their training both in cars and on motorcycles.
It`s quite a sight when you a dozen or so Police motorcycles in full flow.
The downside is we see the result when the pupils get it wrong and the training vehicles ( cars and bikes ) are returned here on recovery trucks.
They all have " Police Driver Training " stickers discreetly placed on both the cars and bikes and that`s how we know it`s the training vehicles.

Stop talking common sense David - it's frowned upon!
I think it's the people who don't drive for a living that would benefit the most though - your sunday drivers and those that never drive except the odd shopping trip.
Either way, more education needed.

Don't flatter him, we will never hear the end of it.:idea-007::idea-007:

I suspect that as technology has improved speed cameras have become more reliable and precise and there is no longer a need to offer a small percentage of speed above the legal limit before prosecuting the motorist for exceeding the speed limit. The outcome of this will obviously favour the authorities and hit the motorist.
It may only be a matter of time before it becomes compulsory to have our journeys recorded on in car computers in order that they can be checked by the police, and drivers prosecuted retrospectively for speeding.
The biggest difficulty I have in maintaining the speed limit in urban areas is the motorist who feels I'm not travelling fast enough and who then sits on my tail for a mile or two looking for a chance to overtake or attempting to get me to speed up. Either way, driving within given speed limits can sometimes put me at far more unease and sometimes in real danger of accident.

I wasn't referring to the vehicle's speedometer.
I understand that speedometers are factory calibrated to over read the speed of the vehicle. i.e. register the speed of the vehicle as faster than it is actually travelling, and that the variation in this calibration can be up to 10% (later fitting of smaller or larger wheels will affect this). There is no reason therefore to be penalised for speeding in a 70mph area if one's speedometer is reading 70mph; you could in fact be travelling at 63mph.
The point I was attempting to make is that the only reason I can see for Local Authorities adding some allowance before prosecuting is to be sure of a conviction. With more accurate and reliably tested speed cameras there would be no need for LAs to add any leeway and they could, if they wished enforce what has earlier been referred to as 'zero tolerance'.

Now that is strange I have little difficulty keeping to the speed limit in built up areas, I veryyquickly get the sense of my speed from the movement of he surroundings as I pass along, and I never allow myself to be bullied into speeding by tailgaiters. In extreme cases I will pull over and let them go past, their problem then if they get caught.
No one can make you break the speed limit, you choose to do it yourself.

Like you Maxi, I have pulled over on occasions to allow someone tailgating me to overtake, or alternatively have slowed down further to be able to emergency stop if necessary without being tail ended. It's not about being bullied it's more about having to take responsibility for someone else's poor driving in order to avoid being involved in an accident.

Tachometers have been doing just that for many years now, and now that they have digital technology, the drivers' opportunities to fiddle them are somewhat diminished! When I was doing QA work with big truckers like Widdowson Haulage in the 80's they were required to submit all - or some, I can't remember which - for analysis. I didn't find out what the result was!

It seems that technology is boxing us in in all aspects of our lives and as I said, I suspect it will only be a matter of time before we must have something similar to a tachometer in the car.

The sidewall will not be significantly more than the bike tyre, certainly the overall diameter of the tyre will be less than the bike one on a 17" rim.
Also it is obvious bikey fella is meaning a 5 mph gain on his speedo when the engine is at a set rev speed. That is even more nonsense, no matter what size of tyre you put on the speedometer will still register the same speed for the same rpm in the same gear.
His 5mph assertion is total bollocks!

Hello Winker,
"That is even more nonsense, no matter what size of tyre you put on the speedometer will still register the same speed for the same rpm in the same gear. "
Absolutely, but the speedometer error will alter, and as speed increases tyre diameter does marginally due to centrifugal force, probably not significant at the relatively modest speeds we now drive on the roads.

I guess I didn't make it clear that I was referring to something that does a little more than count the engine revolutions. I was thinking more of a device that will record a journey from start to end that will record any and all traffic infringements, such as parking on double yellow lines, wrongly entering a box junction and speeding that you could be prosecuted for later.
