M1 'horror' crash

But the photo on the very first item in this thread shows the Fedex appears to have hit the rear offside of the trailer, not straight into the back.

But the impact looks flat, not angled. First point of contact is only 1/4 width in from off-side of cab, he was basically in lane 1 and drifting to lane 2, but not at an acute angle.

My other half was nicked for doing 31mph in a 30 mph limit, cash machine and the authorities had reduced the limit from 40mph recently. Didn't notice the speed limit reduction so took the consequences. The road in question is perimeter of Barking where dual road drops into single road. (Thank god it wasn't me that was nicked, wouldn't have heard last of it )

You wouldn't get away with that if loonr1 was still here

1 mph OVER, honest?

yup, gods honour. She attended the road speed aware course and now gives me a bollicking every time I nudge over the limits, very tiresome.
No such thing as a 10% error margin we surprised me, the limit posted is thee top limit of the speed permitted.

So much for several forces such as Cumbria not operating a no tolerance strict speeding policy then.

Did read something recently about the latest generation of cameras being so accurate that the "leeway" that used to be allowed may be a thing of the past, but 31 in a 30 would be ridiculous even so.

Another one here that thinks the leeway has gone. I've just got nicked for doing 33mph in a 30mph road in Glastonbury on a Sunday morning.

This, if true pissed me off, frankly. One of our cars had graduations on the Speedo in 10 mph increments. Scientific principles of error measurements says that the most accurate you can measure on an analogue instrument is plus or minus half the smallest graduated interval, so in the example given it's +/-5, and that's in lab conditions, taking a careful observation having eliminated parallax as far as possible. Any reading value taken more accurately than that is simply an estimate.

If you look when things were more sensible, rule of thumb was 10% to allow for instrument errors, display and reading, then another 10 mph on top so, if paying attention they must have known they were over permitted limit.

I would suggest that they are relying on folks being so relieved to be offered a SAC that they don't put some of these ridiculous situations, if true, no offence intended, to judicial scrutiny. I mean someone at 31 is making a genuine effort to stick to the limit. At 31 my speedo is a mere needle width over the mark, I know that's accurate as it's calibrated.

Which is another thought, CBA to do the maths at the moment, let's say it was calibrated on part worn tyres, put a new set on what difference does it make?

Edited to add just worked it out on mine, difference in rolling circumference from new to 60% worn is a gnat's under 1.5% so not significant at 30. Fair enough on that.

All car speedos leave the factory reading over by 5 to 10 % to allow for such inherent inaccuracies and tolerances. Imagine the court cases if cars left the factory with speedos reading 10% slower than you are really doing. Speeding tickets, accidents where speed was crucial factor etc.

You can quote all the technological theiry you want, relate scientific principles, point
out parallax error etc, but making sure that needle does not go above the solid mark for 30mph is pretty simple. If it were, say, 26 or 43 mph speed limit then you might have a valid point, but not 10, 20, 30, 40 etc etc.

30 in a 30, Mother Theresa, 31 in a 30, antisocial degenerate. Laughable.

[scenario8]

I really would have expected more publicity had these 31mph convictions become typical or common.

Poor form from motoring groups even if the media weren't interested directly themselves.

Bit in bold, nope, not true. Mine reads a tad under 31 at a true 30. Sample of one. Need more samples? Of all the other vehicles I have had over the years, about 30 of them btw, only one has been in the range you suggest, and that was 8% fast. All the rest were more accurate, including a couple of Citroens that were bang on.

I agree that none under read, that would be a fault.

Your second paragraph, that is true if a sensible margin for error before prosecution were allowed, as it used to be. I don't call 1mph a sensible margin for error looking at the reality of driving today. Sorry, going to have to disagree that in the circumstances being discussed, ie prosecution for 1mph over, if true, is not so simple. Anyway, way off topic now, going to leave it.

[Alucidnation]

Hmmm i thought that manufacturers had to make them over read.

Anyway, done for 31 in 30?

Not convinced.

Bit in bold. Agree.
My E46 is unbelievably close to GPS (Waze) all the way to 100mph.
