For every vehicle that gets 20mpg you need 3 other cars that get 100 mpg in order to average out at 50 mpg.
That would average out at 80 mpg.
The three other cars would need to get 60 mpg.
I'm guessing math isn't your subject.
4 cars travel 100 miles each. If the average MPG is 50, then 8 gallons of gas total will be used. If one car gets 20mpg then it will have consumed 5 gallons of gas. That means the other three cars must each travel 100 miles using only 1 gallon of gas each.
(Edit: In case you're feeling particularly dense, I'll spell it out for you. MPG stands for miles per gallon. 8 gallons consumed. 400 miles traveled. That's 50 miles per gallon.)

More fuel efficient cars have already cut consumption of gas in this country by a noticeable amount. I read somewhere that we are driving more miles but using less gas than we were, I think, 15 years ago. The economic collapse is a factor, but, even extrapolating a good economy, we would be using less gas.
Not to kick a dead horse
but after that whole Obama tire gauge incident consumption dropped like a mofo almost over night...
maintain your vehicles you effing slackers!!!

It most certainly does. For every vehicle that gets 20mpg you need 3 other cars that get 100 mpg in order to average out at 50 mpg.
SUVs are trucks, not cars. They don't factor into the average mpg for cars. 
article that pwns Scarne in the face posted:
President Obama today announced a historic agreement with thirteen major automakers to pursue the next phase in the Administration's national vehicle program, increasing fuel economy to 54.5 miles per gallon for cars and light-duty trucks by Model Year 2025.

Which would average to 80 MPG...

(Edit: In case you're feeling particularly dense, I'll spell it out for you. MPG stands for miles per gallon. 8 gallons consumed. 400 miles traveled. That's 50 miles per gallon.)
4 cars get one gallon of gas each. Three of them each get 100 miles before they run dry. The fourth gets 20 miles and runs dry.
So, they get a total of 320 miles on 4 gallons of gas. Or, an average of 80 miles per gallon.
<edit>Added
If you have one car that gets 20 mpg, it's pretty trivial to figure out what other cars have to average to bring the overall average up to 50. They have a deficit of 30 mpg to make up. Assuming three other cars, each would have to get 10 mpg more than 50 mpg to average out to 50.
You DO know how to figure an average don't you? To use small words...add up all the numbers and divide by how many numbers you used. In your example, it would be 100 + 100 + 100 + 20 = 320/4 = 80.

You are assuming the guy with a car that gets 20mpg drives a tiny fraction as much as the other guys. He doesn't. He drives the same.
Miles per gallon is calculated by dividing the number of miles traveled by the number of gallons consumed. You can only get to 80 if you pretend the one guy only drove 1/5 as much as everyone else.
400 miles traveled divided by 8 gallons consumed = 50 miles per gallon

Nobody is suggesting or demanding people give up their 8MPG pimp mobiles. But it your vehicle gets 8MPG and you are bitching about the price of gas - you are a effing moron!
So the one bitching about the price of gas should be the person driving an electric vehicle?
Seems like the perfect candidate to complain is the one in the 8mgp vehicle.

I don't see any reason not to complain. Petrol is a limited resource and the first responsibility when dealing with a limited resource is to make sure it is being used in the most efficient way possible. People who drive gas guzzlers, IMO, are committing crimes against nature and not only that -- but they're retarded.
Many of you guys would be considered too unethical to be a professional engineer.
