If loud pipes save lives, imaging what learning to ride that thing could do
The crazy stunters who eventually meet a bad ending are just natural selection at work. 2 lane highways here must be deadlier to bikers than interstates.

Again, a driving style that's gradual on the gas pedal, not racing to the red lights, keeping the speed at the limit on highways and driving consistently on the highways all will produce better MPG and save money. Trying to justify the opposite just won't work.
I'm not sure where your argument is trying to go.... Nobody stated the contrary. The counterpoints were simply that fuel economy doesn't necessarily vary as dramatically at different speeds, depending on the vehicle, as what that website presented, and saving fuel is not necessarily the most important factor for the driver.

"I think people are irritated because boring people in boring cars won't get out of the way, and won't stick to the slower roads where they belong...hint hint "
How is driving 75mph instead of 65 mph on an interstate any less boring? Driving on any interstate is boring regardless of speed...it's a flat straight roadway Going 55, 65, 75 or 85 on an interstate is all boring. If you're driving a corvette at 85mph on an interstate it's boring or in a prius doing 55 it's also boring. I've done both. To me doing it in the corvette was not only boring but frustrating because of all that wasted power under the hood that won't be used in 99.99% of driving.
So don't try to say "it's too boring" driving 65mph vs 75mph...either speed is boring
My point is that going 60 vs 75 mph saves me money, so if I'm going to be bored on a straight, flat, boring interstate, then I might as well drive in such a way as to save money.
Another plus by going slower is that in the right lane while driving 60mph I won't have to worry about passing cars (of course for some of you, passing cars in the left lane is the ultimate form of excitement
). By not passing cars, it's easier to maintain a consistent speed, which also improves MPG.
Anyway, all of you can enjoy your higher-speed boring highway drives, while I'm saving money when I'm enjoying my lower speed boring highway drives, but yes I know that I'll be on the highway several minutes longer because of my speed, but I don't think we need to revisit the illogical speed/time/money discussion!

...proved you can go over 100mph in a Prius, FWIW.

So then I guess the crux of it is... what is more important to you: Time being bored or cost of fuel used during that time?

But how much money saved vs time? It is again all a personal decision. If I can get 30mpg at 70mph but 32mpg at 50mph, I am going to choose the faster speed. What is "illogical" is subjective.
I wish I lived in a place where 60 was the right lane. You can be in the left lane a lot at that speed, especially on 405, where the right lane often moves at 45-50. You'd love it here! Think of all the money saved
Thanks for the good wishes, and you can enjoy your turtle crawl - just stay in the lane where you belong, and maybe stick to scenic state highways as you have nowhere to go and all day to get there anyway

With DC traffic it's option C, 26mpg at close to 0mph.

Back in 2008, when gas prices were getting expensive, I remember driving my 2000 Intrepid up to PA to go to the Ford Show in Carlisle on one brutally hot June day. Just out of curiosity, I tried hypermiling it. No a/c (this was early in the morning, before it got hot). Tried to keep the speed around 55-60, which was hard to do, and I did get up to 65-70 once or twice. MPG on that run was 32.1 mpg, which I think is the best I ever got out of that car.
A few months later in October, I went up again, for the Fall Carlisle swap meet. This time I averaged more like 65-70 mph, with perhaps an occasional jaunt to 75 or 80. Flow of traffic, more or less. Fuel economy on that run was 30.82
The following week I went back up for the show in Hershey, PA. This time, I was running around 70-75 for the most part, and again getting up to 80 on occasion. This time around, 30.01.
So really, not a huge difference IMO. And going at those slow speeds like I did the first time around can actually be dangerous, when there's too much speed disparity between cars. Now, that first time I did it, everybody seemed to be going a bit slower, no doubt in reaction to gasoline that was approaching $4.00 per gallon for the first time. So, it wasn't as bad. But, now that people have gotten used to high gas prices and are driving faster, I'd be afraid to go that slow on my PA run.
Making that trip up for Hershey can be pretty adventurous too, as sometimes you'll get some old fossil who takes their Model-A or something similarly slow and putts along at 35-40 mph.

I agree...if you're really only getting 2mpg more by going 55-60 vs 75mph, then I wouldn't worry about the MPG savings either. But from what I've read and experienced, most people will see a lot better MPG improvement that what you're seeing, but it does depend on the specific vehicle. That's the way statistics and averages work out.

Overall, well stated.
I would only add that, in many modern models. say a BMW, Audi, Chrysler 300 or Lexus (there are many others) the fuel savings one might see are so small as to not be of any major importance to them.
Im not advocating speeding, but at least to me, going 60 on a 70 MPH Interstate highway just to get 32mpg .vs. 30.5 mpg, over the length of a 5-6 hour trip seems like poor justification for running 60. Now, if the mpg ratings were 32 .vs. 16, its a different story altogether... but in reality, it isn't.
