2003 Honda Accord 4 cyl gas mileage on the highway

Dunno if this last paragraph was directed at me or not. Engine is most
efficient at arond its peak torque area. (at least for non vtec
engines) I'm not sure about them, having not had much experiance of
them. I personally didn't learn about anything at high school (since
i'm not american, and thus never went to one) but what i learnt about
cars, i learnt in my teens, working on my fathers rally car, and doing
the old economy rally's. Those were fun, slingshotting the car around
the peak torque area, and using a saab freewheeling unit in between.

I think that is close, but at peak torque, most if not all engines
go into fuel enrichment. So, they won't be terribly efficient
there. Highest efficiency is typically about 20% or so below the
peak torque for that rpm judging from the fair number of brake
specific fuel consumption maps I've seen. That's still a very high
throttle setting which you won't see in typical cruise.

Why not keep up with the pace of traffic rather then being an hazard?

link between 9/11 and Iraq, the answer is no."

On May 01, 2003, President Bush declared that,
"Major combat operations in Iraq have ended."

"I'm the commander -- see, I don't need to explain --
I do not need to explain why I say things. That's the
interesting thing about being the president.
Maybe somebody needs to explain to me why they
say something, but I don't feel like I owe anybody
an explanation. "
- George "Dubya" Bush

Not neccessarily. Cruise control increases the throttle opening for any
slight incline. Practiced fuel economy drivers will let a little speed
bleed of on modest uphill inclines and then let it build back up going
down the other side.

For *most* drivers, cruise control can improve fuel economy. However,
for those rare drivers who have studied the art of fuel economy
maximization ... ya can do better.

BZZZZT! Yellow flag scam possibilities. Rust is not a reason to
replace rotors. Insufficient thickness, deep groves and warping are all
possible reasons for replacement.

Old story, old scam.

Exactly what does this entail? And doesn't traffic interfere with your
careful anticipation? People doing a constant 50 around here are in
danger of being crushed by Yugos running on one cylinder.

It was probably the A/C and the desert heat that sapped a lot of the power.
In 4th gear, while climbing mountain (in Hamshire & Vermont) I'm able to
maintain 105 mph, but that's on a nice cool (65 degree) day with no AC
equipped. If you're racing up a hill and your speed is under 100mph, 3rd
would be the preferred gear, instead of 4th. While climbing a particularly
steep hill in 3rd gear at high speed, frequently I'd have to pass on the
right (those pick-up drivers have a lot of attitude, especially when there's
a small car bugging their ass on the left lane).

30 mpg is about right for aggressive driving situation and slowing the speed
down to 50 mph would return a huge improvement on fuel consumption (like 40
mpg or 50mpg on a cool day with fairly level grade).

Also, after 250,00km of driving, I've yet to see my temperature gage go
beyond the 2/5 mark. The big engine compartment with lots of free space
helps.
