Re: House Price Declines: Buy the Numbers
I should point out that improvement of CAFE standards doesn't necessarily yield the scale of improvements you may have in mind.
In the 1975 to 1985 period, CAFE standards as well as high oil prices led to an overall decade long drop in US oil consumption.
However, in 1975 the average MPG was 12.9. CAFE in 1985 was 27.5 (from an 18 CAFE in 1978)
http://www.csa.com/discoveryguides/e...g/overview.php
Assuming that Americans drive 15000 miles a year - the difference meant a savings of 617.3 gallons per car per year, more than a 50% reduction (15000/12.9 = 1162.8 - 545.5 (=15000/27.5))
Today the average MPG is around 24.6 from a peak of 26.2 in 1987

Let's say the average MPG is raised to 33 implying a CAFE standard of 36 or higher.
The above calculation for 15000 miles/year driving then becomes: (15000/24.=)609.8 - 454.5(=15000/33) resulting in a total savings of 155.3 gallons per year per car and a 25.5% reduction.
Having an average CAFE of 33 or higher also pretty much guarantees the outlawing of SUVs and other light trucks.
To summarize:
A more than doubling of CAFE standards from 1975 to 1985 resulted in a halving of automotive demand for oil via a doubling of average MPG as well as a per car savings of over 600 gallons of gasoline per car per year.
An increase of present average MPG by 34% would only reduce consumption of gasoline by 155 gallons per year, a bit over 25% reduction.
The use of oil for personal transportation via the model of one car per person is simply far too wasteful of oil under any type of high oil price scenario for Americans to be able to compete.
CAFE type conservation efforts will not help enough.
