Don't do the math for homeless people. Most people live in homes. Homes usually have electricity, unless you live in a 4th world country. All buildings have electricity. Just park and plug in.
You need to go to a gas station BECAUSE there is no supply of gasoline straight to home. Homes have electricity. Even in sub-Saharan Africa, South Sudan, Yemen, remotest village in India. I don't know where you live, but if your home doesn't have electricity, your country has bigger problems to deal with than buying Teslas and DC Fast Chargers.
