True, but try that same maths trick over 60 million folks in the UK, not ten folks.
Feel free to come back when you understand the Central Limit Theorem
and a Normal (or Gaussian) distribution averaged over millions of folks, not ten.
You do realise that the vast majority of those 60+ million folks have more than the average number of legs? Feel free to come back when you understand the Central Limit Theorem
and a Normal (or Gaussian) distribution averaged over millions of folks, not ten.
And yes, I get that the "50% of people have less than the average IQ" is true for IQ because of how it is defined, but there are a lot of cases where it isn't...
Before I retired, I was earning less than the average (read mean) income, but more than the median

I do the same and speed every day.
If you don't know better then I pity you, I know my capabilities, I know the weather conditions, I know the traffic, I know what car / van / truck I'm driving, I know what load I'm carrying... so obviously I can make a better judgement on my speed than some random number on a stick.
Exactly what scientific approach do you think was used to set the limits and how often are they reviewed ? It's the same limit at 6am on a sunny summer morning as in the snow, in the dark, at rush hour !
I can tell you in the last 25 years I've had no accidents.
Been let off with a warning approx 10 times
Had one SAC
Had 4 sets of 3 points and fines
Have held a clean license for at least the last 10 years
Now, what was your point ?
I totally agree and speed limits and nanny state politics really annoy me.If you don't know better then I pity you, I know my capabilities, I know the weather conditions, I know the traffic, I know what car / van / truck I'm driving, I know what load I'm carrying... so obviously I can make a better judgement on my speed than some random number on a stick.

Its like tax on sugar and several other draconian measures to "protect" when its all about the cash raised.
I judge the road and my speed and will happily give it the beans if I think its safe and I feel like it.
The speed limits take the piss the stopping distances are way less and cars are much safer.
If you want to rigidly adhere to the posted limits thats your choice and equally if i want to overtake you I will

Of course. 1.95 (or thereabouts) < 2.Gojira said:

We weren't talking about those cases.Gojira said:

Good for you. I hope it works out.Back on topic, an old anecdote from my old German mate Dieter:
When in speed limited countries, pick a number you feel comfortable
with close to the limit and set the cruise control to that. Try to
concentrate on what you are doing, even though the monotony
will get to you.
When back home in Germany, don't use the cruise control, just use
your brains and drive the road at a variable speed you feel comfortable.
Slow down for the tricky bits, speed up for the easy bits. Much more
variable, much more engaging for the brain.

Genuine question, what if any speed limits should there be? Its like tax on sugar and several other draconian measures to "protect" when its all about the cash raised.

Variable ones, set on scientific reasoning not Political grounds.
They could change and notify satnav instantly or vary with weather / time etc
I've variable in bad weather limits in france and the US but not that level. They are just 'on/off' limits. They could change and notify satnav instantly or vary with weather / time etc
I think some 'instantly changeable' limit would cause just as many problems as it's solves, never mind the cost of it.
While not having been on a speed awareness course, I had reason to slow down in that I wanted to spend less on fuel.
Consequently, I drive at 60 in lane 1 now to and from work and theres just... no stress. Nothing comes as a surprise either, as it's easy to maintain decent distance to the car in front.
I cringe for the poor guys moving in and out of lanes and going up and down from <10 to 80, sitting behind other cars. They must arrive at work absolutely enraged some days.

You might want to change your username too. Consequently, I drive at 60 in lane 1 now to and from work and theres just... no stress. Nothing comes as a surprise either, as it's easy to maintain decent distance to the car in front.

We had this discussion on here a while ago, another PH'er must have been on the same course. I thought they said that the difference was 5mph, but may depend on the speeds from which you started.
but it isn't BS, if you think about it. The rate of stopping will have an effect as well, but the same vehicle with the same weight and brakes etc, if it starts braking at the same point, will take a greater distance to reach a complete stop if it starts with a higher speed. And from that you can work out the actual speed difference at any given point, and the point at which the slower car has reached 0, the faster call will have some distance to travel.
Which if you look at tyre tests is easily the difference between the better tyres and the ditchfindersbut it isn't BS, if you think about it.

The point being made is that is braking from 30mpg at point A stops you at point B, had you been doing 35mph at point A, you'd be doing 18mph at point B. That applies if you're in an F1 car, or a Model T Ford. It applies if the car has ceramic discs with expensive tyres, or drum brakes with cheap tyres.
Actually, probably doesn't for a car with significant downforce, the physics is different.Sheepshanks said:

I actually found the course was rather good, espcially the stat that 80% of children hit by a car at 30mph will survive, 80% of childen hit by a car at 40mph will die. When you consider that (am assuming it is true) then those few mph over 30, for what they acually achieve, are pretty much pointless. So ever since I bimble around town obeying all 30/40/50 and NSLs.
Why don't you bimble everywhere at 30 so most children that you hit will survive, whatever the posted speed limit?V8RX7 said:

You must be the only person who didn't see those awful adverts thenHow many children die if they are taught the green cross code and looked after by responsible parents ?
Alternatively if 30 is the safe speed for passing homes where children may run out, then why are there NSL outside thousands of homes ?

Braking from 30 mpg eh, glad to see you're on the ball as ever. 
And no. That's not how it works.

Speed = Distance / Time
Fact is, if you go faster you get there sooner.
If you're doing 100 on the motorway, overtake a car doing 70, and 2 mins later you hit a traffic jam, when the car doing 70 rolls up next to you a short time after, explain how you got there sooner?Fact is, if you go faster you get there sooner.
In the 90s I got to 6 points, with 18 months before the first lot of 3 points dropped off. So I decided to stick to the speed limits rigidly for 18 months. I live in the London suburbs, and the fact is, journeys didn't seem to take me any longer, although my tank of fuel lasted much longer. A few trips up north did take me longer, but not much, maybe 15 mins or so.
