But most of those things are present -- in greater quantities -- in
any sort of mechanized transportation.
Bill Sloman's original claim was: "... an e-bike doesn't generate any
CO2.", which is patently untrue. Had he said : " ...an e-bike doesn't
generate any more CO2 than other comparable modes of transport, that
would have been nearer the truth.
My point is, ANY transportation medium consumes energy. Once you
decide what is "acceptable" (in terms of convenience and cost)
for transportation, you've defined the size of "settlements".
How much distance can we cover in a specific amount of time?
If you want to avoid all such conveyances, design settlements that
allow everything to be in walking distance. The "original settlers"
knew to make those settlements small because the cost of traveling
and transporting goods over any meaningful distances was high.
[They leveraged waterways to reduce those costs but thus constraining
settlements to reside ALONG those waterways]
We've steadily allowed settlements to sprawl. That means we need
conveyances that can navigate those sprawls for some "reasonable"
sets of time and cost. Without regard for externalities (because
we NEVER address those!)
Now, we try to enhance the effective efficiency of our transport-settlement
relationship artificially. E.g., I'll buy a *case* of goods to make my
driving across town feel more efficient (by making it less often)
