Safe Speed Forums

Impossible to answer.
Thats why speed limits are arbitary from a safety point of view. If you want to have an environmental impact then speed limits make sense except in certain circumstances when going up hill sometimes you can coast up a hill quite quickly exceeding the speed limit and that would save fuel, but in order to keep to the speed limit you have to slow down and change down a gear and this costs fuel. So even in case of Environmental protection speed limits are not 100% sensible.
(I said 100% sensible as in sensible in some cases and not in others.)

And you were asked not to answer.

We know what most members of the forum would consider to be safe, we want TSMs view.
