What I want is: for the engineers to pick a speed limit that aligns with the design speed. If that's 70, so be it, if that's 60, so be it. I don't care.

So, did bringing in the "cost thing" accomplish your intended goal of getting the councillor's attention?
What do you mean by "variable speeds" along Taylor? The speed limit is 60 along that entire stretch, and I didn't see any indication that this is going to change. Or, are you just assuming that Taylor east of Waverley was not also designed to a higher design speed?
Since you seem to be an expert on the subject (by your own admission, you've read several publications on the topic, and have at least a cursory knowledge of TAC guidelines), are you able to tell us what the actual differences would be in terms building the road to a 10km/h higher design speed? In terms of widths, grades, etc.? I'm curious.
To me it seems like common-sense that a factor of safety is incorporated into any design, whether it be road, building, or other. But that's just me.
