whoever controls the gas stations at your shopping strip (and onsite farm gas tanks) controls you in that situation.

I am prepared to drastically reduce my need for fuel in various ways. For one, I can cover tens of miles every day by bicycle. Of course, that is with just one bag of stuff.
The key to survival would be to virtually, if not literally, ween yourself from the need for fuel.
