Greenshed. This seems to be the fundamental dichotomy.
You want speeds reduced so that when collisions occur the injuries are less severe.
Safe Speed, AIUI, want drivers to drive at such speed and in such a manor as to avoid accidents
Less speed IN = Fewer serious injuries OUT.
The incidence of collision is exponentially (^2) proportional to speed. Seriousness of injuries is exponentially (^3) proportional to the speed at impact. Death on impact similarly but (^4) as I recall.
The public road network populated by the public (funnily enough) will never be populated by sufficient highly trained and skilled drivers to create an environment where those highly skilled can use that skill in a way that will protect those who drive but are not as able; say the older, less interested and to a large and significant extent the young and the novice. It remains a fact, even the best commentators in Safespeed cannot deny it, that more speed gives less time to react and mitigate the unexpected. When the unexpected occurs, it always does because we have uninterested and less skillful divers of all types, the increase in speed creates a bigger danger. This, I would summarise, is the basic premise of a system of speed limits; they mitigate the masses to a reasonable level of risk from expected behaviour. They don't work or are reduced in effectiveness if they are ignored.
Take the boxing ring with a number of children walking round it.
1. They walk slowly and at all times they are able to miss each other; well there may be a clumsy one that knocks shoulders but causes no harm.
2. Get them all to skip, a few more collisions occur because the space is being used up quicker; most knocks are again harmless but there is one clash of heads and one has to be attended to by the nurse.
3. Get them to run reasonably fast but not as fast as they feel able, oh dear! More collisions occur and this time the nurse is starting to run out of bandages and asprin.
4. We then get them all to run around in the same direction and collisions and subsequent injuries reduce to the same level as when they were skipping.
5. Now, after replacing some of the injured so we have the same amount of children in the ring we get them to run in the same direction but as fast as they feel able to. Injuries, serious injuries increase.
6. Finally we reduce the numbers to just 8 in the ring and get them to run as fast as they feel comfortable but this time in any direction; every time this is done we have serious injuries resulting and frequently.
I haven't done this experiment but you can easily see that if it was done that you would be able to confidently predict the outcome as I have here.
Yes, there is a dichotomy but which is the publically acceptable and practical solution?
My father, a pretty good driver still and in his younger days excellent in my opinion but is now less able to react and I now see some mistakes made when I am out with him. My daughter, pretty good for a 4 year novice, makes some elementary mistakes. Both of them could put themselves in positions that would come unexpectedly on the driver using the Safespeed method and be in excess of the speed limit, a driver who is willing to increase risk on the strength of their self belief in their skills and capabilities yet when those fail, for whatever reason, the extra speed brings in the laws relating to speed and injury outcome; more is more.
My father carries my mother in his vehicle; my daughter carries my grandchildren, the extra risk resulting from the adoption of the Safespeed side of the dichotomy is not acceptable.
I know that anyone can be killed or seriously injured at or below the speed limit; that is not an issue; what is an issue is that there is an increase in risk when the speed at which people are allowed to drive increases.
Unfortunately for Safespeed they are in a minuscule but vocal minority campaigning for something that is socially unacceptable and scientifically proven to be inefficacious.
