Suppose we set off on a 10 mile trip that looks like this.
B’ Spokes:
If you think your average speed would be 40 mph… Wrong. It’s much lower.
Well OK, but we would save lot of time by increasing our speed on the highway section from 60 mph to 100 mph… Wrong.
Fine, but we need faster roads to accommodate more cars as the faster the road the better the throughput is… Wrong.

I’ll note my intention on sharing this is to help dispel our societies fixation on “zoom-zoom” or more correctly spelled out as “Faster vehicles cannot be delayed in the slightest while slower cyclists and pedestrians will not mind at all going even slower with additional road crossing delays and going out of their way by 20 minutes or so, as even a two second delay to a motorist is an extreme hardship.”
We need to reinstate the mentality of “You get there when you get there” as well as “Drive carefully” and get rid of freeway type engineering (where bike/peds are prohibited) on local streets (where bike/peds are present).
