@Gork @three_trains_in_a_trenchcoat
My understanding is, when they design a road they do calculate the "engineering speed limit", the safe speed given road geometry and surface and visibility, etc., but then they mostly ignore it and assign an arbitrary limit from the standard list for that type of roadway.
We botched raising the limit for 400-series. We should have gone to 120km/h with actual enforcement, but what we did was 110 and a wink, and now 1 in 3 drivers do 130km/h.
