Therefore I'd assert it's best if all drivers stick to the speed limit (or at least thereabouts) to mitigate against such variables as driver concentration.

OK,

why are some roads 20, some 30, some 40, and so on?

(No, I am NOT advocating speeding, btw.)
 
Which was in response to noseall's claim that because he largely sticks to the speed limit and doesn't have any points. He isn't in need of further training.

To help you reflect on your trolling.

Do you think it's safer to drive with your eyes open at 30mph than 20mph with your eye closed. Its a simple question.

I don't think I'm a good driver, nor do I have a host of people to compare against.
I'm an adequate driver, that drives deliberately and refrains from driving at speed.
Maybe I'm just lucky I've never had a speeding ticket.
 
zero might be good for you if you think 20mph is ok with your eyes closed.

Statistically you are far more likely to kill or injure someone because you emerged at a junction without looking.

At that point your speed will be a few mph and completely irrelevant.

I'm happy to have a sensible debate with anyone about road safety. But it has to start with a basic level of understanding. The basic requirement is a speed that is no faster than that which enables you stop safely in the distance you can see is clear.

You look at the road, you identify hazards and potential hazards. You prioritise these hazards and you drive accordingly. In some situations 20mph is too fast.

Road A - A narrow road with parked cars either side, side roads and no sight lines of the pavement. There is a real risk of a pedestrian emerging between a parked car. So in this case the distance you can see is clear is around 8-12m. A safe speed would be no more than 15mph.

Road B - A largely empty dual carriage way, so no access roads and a central reservation. You can see at least 300m is clear. To save you the maths you can stop safely in 134m at 80mph, which by the way is the design speed for motorways of 2 or more lanes.

Now imagine Road A is a clearway and no parked cars. You can easily see the pavement, driveways etc and that there are no pedestrians, for arguments sake you can see 50m is clear. What is the safe speed you can drive?

Now imagine Road B is busy there are lots of cars. What is the safe speed you can drive?

Still think choosing a safe speed is just physics?

Eyes open but looking at the kids in the back?

You cannot assume everybody concentrates on driving. Hence the need for speed limits, as police traffic enforcement has just about disappeared.

I, like I guess most other experienced drivers, assume everybody else on the road is incompetent until they prove otherwise.

And even the best drivers make mistakes.

I'm not quite sure what you're asking tbh and I'm not inclined to get into a backwards and forwards where never the twain shall meet.

Speed limits are set according to the type of road and surroundings to improve safety and reduce collisions. So to take extremes, a street in an extremely built-up housing scheme will be 20 and a motorway will be 70.
