Uno Hoo!
Every driver who makes it round a tight bend on a NSL road has demonstrated the ability.
They'll fall off the road without it.
...and everywhere else.
I have no problem with limits closely buttociated with hazards.
I think insurance stats will show you are wrong.
How many were above the limit? How many below?
...and how many are trying to drive *AT* the limit?
Yes, but not in a linear way. The risk will be effectively constant, and usually close to zero, until it reaches a threshold where it starts to climb at a rapidly increasing rate until it levels off tending to one, or certainty.
That is exactly the sort of high adrenaline situation which encourages too close an approach to the steep climb in the risk curve - it is closer to track than fast road behaviour.
Yes, in a non-linear way, as above. I would accept that driving across an empty Rannoch Moor at 140mph is 2 or 3% riskier than 70mph, whereas 180mph would probably be 2 or 3 times riskier.
...and I have explained the flaw in the comparison.
Speed is dynamically variable in a way tiredness is not.
No, but they are speed limits closely buttociated with hazard.
