I have several vehicals in my household.

1. 04 F150 4X4 13-17mpg

2. 98 Jeep Grand Cherokee 4X4 17-19 MPG

3. 01 Suzuki Swift aka 2 door speck. 38mpg

That Jeep used to big a big SUV now it dosen't look big at all. I use the Suzuki swift to drive back and forth to work.
42 miles R/T. The truck is used to pull my RV and for long trips in comfort.

If you have your budget in order and don't live life paycheck to paycheck you can do alright.

Another reason for high prices is a pump and dump factor.
Just like housing is deflating, gas prices will have their time too.

I am old enough to remember the gas lines and limiting in the 70's. I also remember in the early 80's gas was at $1.20 plus then it came down to .87 or so. It will take time and it is going to hurt. As for food, expect shortages due to idiots that believe in grain derived foods used for fuel. farmers are selling to refineries because they get more money for it.

Hang on it is going to be a wild time.

I should add that I am invested in energy so, I enjoy getting a dividend that offsets the high costs.
