I had a Saturn when Clinton was President, and I remember filling that take for less than $10. Now I have a Yaris, also with a small tank, and it cost me over $48 last time I filled it.
That got me thinking: how hi would gasoline/diesel prices have to go before it really effected my life? Remember, it is not just the cost to refill my car, but also the added cost to transport and even produce all the things my family consumes, and it is the hit to the economy that having everyone else having to pay more for everything. I keep coming up with the number $100/gallon. At that point, I would have to start cutting back.
Still $48 is psychologically shocking.
