Buy an electric vehicle. No kidding, avoiding the pump (and paying the petroleum industry tax) was my #1 goal (not saving money - I live in CA where kWh prices are very high).

And I can't express how much I love not feeling anxious every time I drive by a gas station to worry "do I need to fill up now"?

Filling up at home every single day is much more serene. We also have a 2nd vehicle that's non-EV for trips.
