The question of where mopeds/scooters park shifts to how much (or what kind
of?) pollution they emit...

I know that many small engines emit proportionally more polution than cars
(which is among the major reasons I--and I assume most of the people on
this list--use a human-powered lawn mower rather than a motorised one), but
in another context....

...which reasonably leads one to wonder if the 50-100X assertion about
mopeds is approximately correct and how measured. I would assume you'd at
least want to standardise the comparison by distance. So if a moped or
scooter gets, say, 150 miles per gallon of gasoline and a car gets 25 miles
per gallon (of course I know there's a wide range of fuel economy numbers
within the different vehicle classifications; a subcompact four-passenger
gasoline-electric hybrid might get almost 50 mi/gal, my midsize car gets a
gasoline-equivalent fuel economy of 33, but a subUrban assault vehicle
might not get much more than 15, and I'm sure there's a lot of variation in
mopeds, but just to start out the moped could be six times (assuming the
150 and 25 figures) dirtier per gallon of fuel to break even with a car per
mile, so the "fact" that they are as polluting "as 50-100 automobiles"
(presumably all going the same distance) would seem to mean that they would
have to be 300x-600x worse in the combustion of a given volume of gasoline.
And maybe they are, but does someone have an impartial source to document
that?
Now go have a beer,
