Could be one and the same..... :roll: well they're already saying that about SS posters, so it's clearly not beyond their wit to do so.

A Gatso there would mean that they'd be driving down the hill with their foot on the brake rather than the accelerator, which would make life safer for me and for every other cyclist on that road. The limit is 30, which is sensible here, and there's no requirement for anyone to go faster. Why not have a camera?

And how do they know how much they have to brake?

While they’re watching the speedo they’re not watching the road ahead or where they’re going.

One of the main arguments here is that motorists who speed have better powers of observation and judgement than those who don't. If I don't accept this argument then I'm not going to accept any conclusions that follow from it. I do drive, and I know that I can watch my speed and the road, and even check my rear view mirror from time to time.

I'll bet you don't know your speed 100% of the time though which is what automated enforcement is asking you to do.

How often do you check your speed when riding?

No, that's the wrong way round. What you said was effectively; "You speed therefore your observation and judgement are better"

I don't think anyone here has ever said that.

What we're saying is that good judgement and observation are crucial skills. The ability to stay at or below an arbitrary number is not. Current enforcement shifts the emphesis from the crucial skills to the unimportant ones. If good judgement and observation are well honed and relied upon, the speed limit is largly irrelevent as the motorist will always automatically default to the safe speed for the conditions (which in an urban setting is just as likely to be well BELOW the limit as at, or above it).

If you abdicate responsibility for selecting your own speed and simply do as you're told, then you won't be thinking about whether a different speed (faster or slower) would be more appropriate.

I believe that even the Gatsos allow some margin, 10% + 2mph is what I've been told. So if the limit is 40 and you hit 45, then you're still legal.
Maintaining a speed within this margin (and remember you're allowed to go below 40 as well) is really quite easy, with practice.

most of the time, yes but it's still possible to have the odd blip here or there especially on a downhill stretch.


I'm still interested to know how often you check your speed while riding your bike - and knowing the answer already perhaps you can instead tell us how you can manage to ride safely without knowing your speed.

I don't have a speedo on my bike. I had one once, so I know what 30mph feels like and I don't ride that fast now; I'm probably in the 16-20 region most of the time. I don't "cycle furiously" which is what cyclists can get done for instead of speeding.

But it requires MORE concentration to maintain a set speed than it does to just drive at a safe speed.

So you can still ride safely without knowing your exact speed.

Well guess what?

I've read this a few times and can't quite get my head round it. Are you saying that drivers should just drive at a speed as dictated by the limit, rather than choose their own speed?

Don't be silly.


But it isn't silly - it's the ultimate consequence of the argument you are offering.

You're calling for speed limit compliance with utter disregard for the other factors. I'm telling you that it is NOT safe to ASSUME that those other factors will be preserved as emphasis on speed limit compliance increases.

Sorry, I'm missing this point, are you saying that I'd be satisfied to see a higher casualty rate because it would prove my argument; or that a higher casualty rate is an inevitable consequence of inflexible speed limits enforced by unthinking machines?


Ultimately it boils down to this:

Road safety is finely balanced. Crashes are very rare and serious crashes are far less common still. The factors on which our amazing performance is founded are subtle mental skills provided by our road users. If we change the messages, and we're effective in doing so, those 'subtle mental skills' shift. I'm certain that they are shifting for the worse because we're giving people oversimplified targets to aim for.

Got me thinking too. I believe it should read like this

Safespeed has proposed, and then used as the basis for further argument that:-
If you're concentrating on keeping to the speed limit you aren't concentrating on the road and;
If you abdicate responsibility for selecting your own speed and simply do as you're told, then you won't be thinking about whether a different speed (faster or slower) would be more appropriate.

I'm sorry, but how can you possibly know you're riding safely for the conditions if you don't know precisely how fast you're going?

Speed limits, like all safety limits, are set for the worst-case scenario.


Never in a million years. The worst case scenario is zero mph and it's extremely commonplace.


I was using hyperbole, but it's clear from the context what point I was making.


Yes, it's perfectly clear. You think speed limits are set for some 'reasonable' worst case scenario. But that's still wildly wrong. Consider this from the PR I linked:

Quote:
The truth is that 'speeding' or 'exceeding a speed limit' is not, EVER, IN
ITSELF dangerous. There is no magic number that marks the difference between
safe and dangerous. Neither is it a simple matter of suggesting that 'we must
draw a line somewhere', because the safety of a speed varies wildly with
circumstances. In fact if the speed limit:

* is right for a Porsche, it's wrong for a van
* is right on the straight, it's wrong on the bend
* is right in the dry, it's wrong in the wet
* is right when it's quiet, it's wrong when it's busy
* is right for a novice, it's wrong for an experienced driver
* is right during the day, it's wrong during the night
* is right when it's clear, it's wrong when it's foggy
* is right when the road is wide, it's wrong when the road is narrow
* is right when the pavements are deserted, it's wrong when there are
pedestrians about
* and so on, endlessly

Drivers naturally - and accurately - take account of these factors. Road safety
depends on them doing so. The speed limit is blunt and imprecise, but in the
days of discretionary enforcement by Police officers served us well. These
days, with camera enforcement, the speed limit is gradually becoming a target
and gradually replacing the previous safe behaviour.

In fact the speed limit is just a PROXY for the desired behaviour. The core
problem is that speed cameras have promoted the proxy beyond the status of the
desired behaviour.

No, I'm saying that pedestrians should not be given a less-than-50% chance of survival. I'm not arguing that you have to drive at 30, simply that you shouldn't be going faster than that.


And in a :40: ? Or a :60: ?


A certain degree of pragmatism here. If the speed limits were set to 30 or below on all roads except motorways, journeys would take too long, so higher speeds are permited on roads where there are considered to be fewer hazards. 60mph roads don't have pavements, houses and shops as a rule.


But it really isn't right is it? Lots of :40: roads have plenty of pedestrian access - yet they are not considered 'deadly to pedestrians'. If the 'it's 30 for a reason' argument held any water at all, we'd have to get rid of all those suburban :40: s immediately.

The factors that actually deliver safety are completely different.

Not to mention tens of thousands of 60mph roads with pedestrian access; even regular pedestrian use. Round here it's very common to find pedestrians walking on the road itself in 60mph zones.

This is a REAL pissing contest isn't it?

In fact, its a six storey air-conditioned pissing contest, carpeted foyer, adult TV, lifts playing Pink Floyd, 24 hour porterage, free bar, all-you-can-eat restaurant and a 40 foot neon sign saying "THIS IS A PISSING CONTEST" (Black Adder original acknowledged).

Sheeesh :roll:


I would have thought that a pissing contest was really characterised by the inherent uselessness of the subject matter.

Since we're discussing life and death, I don't think it's even remotely fair to call it a 'pissing contest'.

It most certainly is NOT one of the main arguments here.

If you want 'main argument', it is this:

Excessive concentration on a minor safety factor is wasting life saving resources at all levels in the road safety system.

Between Barnet and the M25 there's a NSL road with a narrow footpath alongside, leading to a pub and a few houses. Walking to the pub is extremely unpleasant, not because people drive along it at 70 but because they drive at 90, and they'll still be doing about 70 as they come into Barnet itself. I've never seen any cyclists on the road at all and I'd not ride there myself. There have been fatalities on the road so it actually qualifies for a camera but Barnet Council seem to be opposed to cameras even more than you are. IMO it needs two; one in the 70 section and one in the 30 section.
