SPECS3 average speed cameras launched Motorcyclists beware

I wonder how accurate speedometers are at 20 mph.
Would it be possible to sue the manufacturer if caught by a speed camera when the speedo said you were not exceeding the speed limit?
This goes for all speed limits of course.

According to MCN, the A537 Cat & Fiddle is one of the first places earmarked for this. A favourite biking road, now with a blanket 50mph limit (same as virtually all the decent biking roads in Derbyshire).

Rear facing SPECS are the answer to the enforcers' prayers. I can hear the tills ringing already.

Admittedly there are some bike-riding loonies who do stupid things on this road, but a blanket 50mph is surely not the answer. If I recall correctly, only about 6 percent of accidents are directly attributable to excess speed.

Get your own back - keep within the speed limits. Might not have to visit a relative in hospital as well. Win Win ennit?

I'm not advocating breaking the speed limit I'm asking what if you thought you were legal but the speedometer was not fit for purpose. A couple of years ago I bought a second hand XJS that under read by 10 mph at 40. I only found out thanks to my satnav.

But we all know they are not accurate, they nearly all over read.
This also applies to the odometer which means when you sell the car & quote the mileage you are giving a false representation as it is in fact less than the indicated figure. Of course if you try to correct this that is also illegal. Heads you lose tails they win.
Where's the Motorist's Revolutionary Front when you need them?
I still think its strange that speedo accuracy is not part of the MOT if speed (not considerate driving) is so important

The saftey people/police are going about this the wrong way if they are really serious about reducing speeding.

The truth would appear to be that they want to fine people.

Here is the evidence:

They want us to keep to the speed limit but make no attempt to restrict the top speed of new vehicles to 70-80mph.

The current cost of GPS equipment is so low and small in comparison to that of a new car - All cars sometime in the future should have GPS along with a way to pickup updates while passing update transmitters along the way. This way, the cars would know where they are and the upto date speed limits.

Where limits changed suddenly or temporarily, mid range RFID could be used to update cars with new limits... The cars could also report back giving confirmation of the updates.

I am all for freedom and no restrictions, but REALLY... are the saftey people serious in wanting to have us all obey the speed limits?

No.

I think its a secret plot to cut congestion. The way they are going on, none of us will have a licence, we'll all be walking or cycling. Make us all fitter and cut down on hospital bills to boot.

There's another sinister reason; they will have a record of where and when each of us travelled anywhere. No doubt this will be stored for ever more.

SPECS is flawed as a way of inceasing safety. If you are held up in traffic you can then drive as fast as you like. I think locals will soon be able to calculate the time between cameras and hit the stopwatch as they pass the entry camera.

What's needed is a simple sat nav add on so it can warn if you are about to pass a camera too soon. GPS knows where the entry camera is and the distance to the one you are about to pass so can easily calculate the time at which you can legally pass. All you have to do is slow down or stop for a while, then pass.

Thanks Mike,

I drive a Picasso and the Van is a Merc Sprinter and I still get the 3MPH difference. However, I do know that the 'French' computer type speedo does have a problem with converting KPH to MPH and Kilometers to Miles accurately Rolling Eyes

This SPECS 3 looks like the answer to catch all speeders, but when the system is calculating the average speed between any two points in the network, it must look at all the possible routes between those points and use the shortest possible distance between them. If it looks at the distance based on the main roads, but a driver knows of shortcuts, even if the driver isn't speeding, the system will think he is - but he's just covering a shorter distance.

Taking this one step further - if the system is based on the shortest possible route between cameras, a driver could potentially speed if the route taken is a longer one. Mind you it'd take a bit of calculating what speed you could drive at !!!

Does that make sense??
