^ That's a silly, fallacious argument defeated elsewhere in the thread by #-3.

"Definitely" -- no, I've never claimed
certainty, only that the evidence:
-
supports what #-3 and I have said on the subject with respect to reducing speed variance and vehicle conflict.
-
does not support the time-savings framing because prevailing speeds already cluster near the proposed limit, nor does it support the assumed, broad behavioural changes upon which such framing hinges.
And yes, traffic engineering is about tradeoffs, which is exactly why reasonable people can disagree.
