How did the availability of oil in the 70's affect the U.S. speed limit?

Question

I was just reading this interview, here is the question and answer involved:

So that got the US much more involved in the region (The Middle East), correct?

The U.S. was already pretty involved by the post 1967 period, but what it did for the US and European countries, they realized they had taken for granted the availability of Middle Eastern Oil. And, of course, for a decade or so after 1973 smaller cars were built, cars with less horse power, AND THERE WAS A 55MPH SPEED LIMIT IN THE U.S. There was a conservation movement afoot because it was recognized that oil is a non-replenishable resource and also that the North American continent was using up its oil and would therefore become dependent on the Middle East. And because of this dependency, sure, there was a greater involvement, but a greater concern that friendly rulers dominate the oil-producing states.

Answer 1

im not exactly sure...but i think there was some sort of oil shortage and the speed limit was lowered in an effort to reduce the amount of oil consumed. Going more than 45mph uses more gas.

Answer 2

As you said, Carter established the 55 mph speed limit because it was the most efficient. Because many homes were heated with oil, thermostats were to be set at like 72 degrees.

Answer 3

Oh, please, don't give them any ideas again.!!! I hated driving at 55 mph. I almost would fall asleep..
