Cycling 12 mph for 3 blocks to buy some spuds is obviously going to
reduce overall petroleum consumption and save money compared to firing
up the Expedition.
At the other extreme a RAAM cyclist averages 350 miles/day and eats
25,000 calories/day. Since the farmer needs 36 gallons of petroleum
to grow enough food for a RAAM cyclist to make it across the country,
a net savings of 12 gallons would be possible by flying on a
Dreamliner.
A lot of it depends on your speed. If you stay below 15 mph you
really don't need to eat that much more.

A gallon of gasoline contains.. ~30,000 kcal.. A farmer is able to
produce significantly more than amount in the crop kcal. (solar
energy inputs). at least 10 to 1.. probably 20 to 1..
Note: Rice farming in China 150 : 1.
Average mountain bike mpg is somewhere between 300 to 600 mpg(gasoline
equiv). Racing,.road only bikes post even higher numbers..
124,000 BTU per Gallon of gasoline * 252 Calories per BTU / 1000 (kcal
food calories) ~= 31,250 kcal.. (food calories).

After commuting 13 miles each way for two weeks I'm guessing I eat at
least $2 more/day and it's not some overpriced diet like Adkins. It's
mostly complex carbohydrates I fix myself, less than $1/lb.
Driving by myself would cost $4.50/day.
The bus would be $2/day, about the same as cycling.
The really green way to go would be to get an E bike. Just a few
cents of electricity each day.

6%% of petroleum goes to agriculture in the U. S.
That alone tells you your numbers are way off.

Yes. But surprisingly, an electric bike is more efficient.

Not too surprising when you consider that a human has a much greater
range.

Does it cause the same swollen prostate problem for the voter
to subsidize?

You can get a large seat and a fully sprung mountain bike if you're
THAT fat.
Just don't expect to get 15 miles/charge.

:) Nope. The spuds do that.
