I'd be glad to (probably should be a new thread, or a link to an old one), but first, you have to tell me what it was supposed to do. And I don't mean symptom-wise (like the self-described 'increase the average mpg of the defined fleet'), I mean root-cause level. What was the goal? The first step in solving any problem is defining the problem.

This is from the NHTSA site
CAFE | National Highway Traffic Safety Administration(NHTSA) | U.S. Department of Transportation
Corporate Average Fuel Economy (CAFE) First enacted by Congress in 1975, the purpose of CAFE is to reduce energy consumption by increasing the fuel economy of cars and light trucks.

So how did it work? Was it a good government intervention or a dumb one? Some good and some bad? What have we learned from trying it?

The purpose you quoted is what I thought it was... reduce energy usage...

If you only look at that.... then I would say it was a success... the average distance a car or truck can go on a gallon of gas is a lot more than before... everything else being equal...

And they have done it with the engines producing more power and less pollution...

I would like to agree, but the numbers show that the overall fuel efficiency dropped, then started to grow again.

I've started a new thread on this, it is a bit off topic from safety...

Are CAFE (MPG) Standards effective/efficient?

I have a little higher standard for 'success' - to me 'successful' means that they obtained results using reasonably good methods (I'm not expecting perfection, or anything close to it). IOW, I was not 'successful' if I lowered my heating bill by spending $5,000 for a furnace with a few incremental % points of efficiency, if I could have achieved that same savings with $500 of insulation. But in each case I was 'successful' in lowering my heating bill.
