10 to 12 mpg improvement is the same as 30 to 60 mpg

[user removed]

At $3.50 a gallon and 10 MPG, just toss a quarter and a dime out the window every mile and you get the picture fairly quick.

12 MPG saves you a nickel a mile.

70 MPG cost you a nickel, saves 30 cents a mile. $30.00 per hundred miles adds up quick.

The whole topic to me seems ludicrous, a huge debate about whether you are tossing 35or 30 cents out the window. Get a CBR 250 R for $4k and toss 4 cents a mile out the window.

At 4 cents a mile you save $3100 per 10k miles, $31,000 in 100 k miles in fuel cost. I have no problem grasping those numbers.

Err... What's unrealistic about 70 mpg? That IS what I get in the Insight :-) (Actually 71.4 mpg average over about 8 years/110K miles.) Though on a long trip like that, I'd probably get closer to 80 in decent conditions.

Maybe 'realistic' isn't the right term, but I think you know you are not the norm... even my ~57mpg 90 day avg for Helga is not the norm (if it were, I wouldn't be in the top 10 FE list for diesels on an FE forum!!)

Again, any "debate" is only in your mind. The only point of the OP was that the biggest gain for the total population of vehicles is to improve the very low end MPG.

Public health officials push to get everybody doing 30-40 minutes of mild exercise 3-4 times a week. Some marathoners will act offended by this, as if they were being told to cut back. Silly.

Lately i have been getting about 1.38*10^63 Plank areas with my car.

Yeah but you're still only getting 12mpg so the whole argument is pointless. Going from 10 to 12mpg is NOT the same doubling your mileage from 30 to 60. The whole argument is pointless and stupid.

What argument? Show me a post where anyone said anything contradicting what you're saying. This is getting really funny.

You just pretty much PROVED why this argument is valid.

10mpg to 12mpg = 10gal/100m to 8 and 1/3gal/100m = 1 and 2/3 less gallons per 100 miles.
30mpg to 60mpg = 3 and 1/3gal/100m to 1 and 2/3gal/100m = 1 and 2/3 less gallons per 100 miles.

In terms of volume of fuel saved, the volume of fuel saved is exactly the same.

So it's a good thing to drive a Hummer to the drugstore, right?

That is completely NOT the point....
