Magic '37'

No - the difference is intent. In the third option the driver isn't considering their numerical speed at all.
Just like you don't have to look at your speedo to know if you've slowed down enough to go around a corner, for example.

Subtle. It's both 1 and 2.

They may or may not know the speed limit might and they've no idea if they're above or below because the measured speed and speed limit are immaterial to them

I'm not a supporter of brake or anti speed. I'm only anti those that complain if they get done, don't use speed limits as a factor (one of many) for assessing the conditions or think they know better.

All those that go on about being ambushed by a copper in a hedge - are they reading the road?

I've been done. I know the mistake I made and it was an error on my part. I'm big enough to admit it rather than think it was someone else's fault.

Let's put it this way. The speedo will not be reading below 37, they are not allowed to under-read.

How does the law prevent faults from occurring, or second-hand gearboxes being fitted with different final drives etc?

Isn't it something called the MOT?

Speedo not checked on MoT.

Driving at 37 mph in a 30 mph limit is generally an indication of poor driving.

Or poorly set speed limits...

Two roads I use - One is a 30mph and the other NSL... both handle high levels of traffic including articulated HGVs and PCVs

The car manufacturer produced a car that had an appropriate speed measuring device fitted within the rules.

If someone changes something that stops the speed measuring device from working correctly, it can only be that persons fault.

Its not really an excuse is it ?

"If someone is doing 37, maybe the 30 limit is too low" - more nonsense. It's 30 because if a kid does run out, they have a lot higher chance of surviving than being hit at a faster speed.

So how many kids would you expect to be running out on this road pictured by Seesure?



Or this one? - https://goo.gl/maps/uJnNm

The latter is by no means an isolated example. This sort of thing does nothing for road safety because the public see it as without merit. The problem is that people then start to disrespect 30 limits in other places where they serve a real purpose.

It's not an excuse at all, and I didn't suggest it was. I'm simply saying that this:

is nonsense. Construction and Use regulations don't permit a manufacturer to fit flashing blue LEDs and noisy fart cans to Vauxhall Corsas, but it doesn't stop them being fitted. The same regulations don't prevent wear/faults/modifications ruining the accuracy of the speedometer. It doesn't give you a defence for speeding though.

Oh for gawds sake. Just all drive around at 29.99 mph, and ALL the roads in the UK will be magicaly safe, and accidents will no longer happen.

Well, when you're driving at a steady 40 along a quiet road which used to be NSL then you have plenty of time to consult your speedo, and perhaps to reflect on what justified reducing the speed limit - what hazards exist on the road which you had apparently missed in all those decades you had spent driving down that road.

But when you're in dynamic traffic conditions - when you're stopping and starting, speeding up and slowing down, changing lanes, negotiating junctions, roundabouts etc - it's all too easy to inadvertently overstep the limit, particularly if it's set too low, and it's under such dynamic conditions that it's difficult to have your exact speed at the forefront of your mind.

Well no - that is just a stupid comment.
But here is a little piece of wisdom. If you decide to break the speed limit, if you agree with it or not, and you get caught - don't come along crying to a forum because nobody forced you to exceed that limit.
It really doesn't matter "if the road should be a 30". It is, there is nothing you can do about it and showing rebellion simply takes money from you for a course and then takes money from you and gives you points in return and finally takes away the legality of you being aloud to drive.

Such an insightful observation, which has never occurred to anyone else

Not quite true, certain aspects of it are:

Method of Inspection

1. Check that a speedometer is fitted.
2. Check the condition of the speedometer.
3. Check that the speedometer can be illuminated.



Reason for Rejection

1. Speedometer not fitted.
2. Speedometer incomplete, clearly inoperative or the dial glass broken or missing.
3. The speedometer cannot be illuminated

It doesn't. My general point was that the vast majority of cars released from factories over-read, to a greater or lesser extent. How that car is maintained after that is up to the driver/owner.

Does anyone know why speedos aren't made to show exactly the speed you are doing?

As I understand it (I may be wrong) - on delivery most new cars will be accurate - but but as you get tyre wear (8mm as new, down to 1.6mm at min), plus potential under inflation - radius of tyre is reduced and so the speedo will tend to overhead more over time. As speed is measured at the axle and not actually over ground, this means manufacturers take a slightly conservative approach?

As I said, I may be wrong and present no facts, only heresy and welcome any facts...
