Had this crazy dream, though on thinking of it further, it isn't so strange, I'll try to summarize it as best I can.
There was one day a week mandated for non motorized vehicles only where all the major roads were closed to motor vehicle traffic. The freeways were nothing but HPV traffic. However, each of the lanes on the freeway were specific.
It goes without saying the slow lanes were for cruisers, kids, tricycles, and such like. Middle lane for people who can keep a reasonably fast and consistent speed, or for slightly less slow folks to pass the slowest folks, but they had to be willing to slow down if needed.
The fast lane had the velocars, racers, etc. who didn't have to slow down at all.
It was really something to see the freeways filled with pedal powered machines, flowing along at varying speeds commensurate with the lane they were in.
Thought of how easy it would be for people to bicycle from place to place on days like that, when no one was allowed to use motor vehicles unless they were emergency vehicles, and anyone else who had special permission to drive had to stick to the side roads.
Brings to mind also the days in Beijing when motor vehicle traffic was reduced to clear out the air for the Olympics.
Could be, possibly, that if there were enough smart people in power, they could declare a HPV-only day.
Wouldn't that go over like a lead balloon with the general population?
Well, one can only dream.
