MD has dense traffic so you don't see 80 very often. Then again, there is enough traffic that you can't use cruise control very often, either.
I'm sure DoD would turn on and off frequently around here.

I was thinking more of Arizona and New Mexico.

You guys don't know what real traffic is! Try driving on an 8-lane divided highway which has a 55 mph speed limit yet the slowest right-hand lane is doing 60-65 and the fastest left-hand lane is doing 75-80+ and all this in bumper-to-bumper traffic

I got a sample of AZ's flat highways recently. Drove from Phoenix to Tucson on an arrow-straight highway, flat as a pancake, too.
Speed limit was 65 IIRC but people would do 80 even with police on the shoulder.

Sounds like the Dan Ryan, Tri-State, or any freeway/tollway in and around the Chicago area!

So I'm cruising along in DoD getting a 30 mpg readout from the driver info computer and I push ever so slightly on the throttle of an Impala and the car drops back to V8 configuration and my instantaneous mileage drops by 8% down to 27.7 mpg. 27.7 mpg be 'fair' for a 303 HP V8 from the GM guys who have no worthy innovations. I guess the Asian 303 HP V8's get 35-40 mpg because they are full of efficiency and other innovations of which American cars are starved of. 35-40 ss hwy mpg is available in what Asian V8 fullsize passenger car? Or is the 8% number GM media puts out set to avoid frivolous lawsuits? We are talking about a 35-40 mpg car geared for 5.3 second 0-60 times also.

Do you actually have an Impala with the 5.3 engine? If so what kind of fuel consumption are you getting? My SRX can get 30 MPG's on level ground too, but this is usually momentary...
On the government fuel economy website, one owner of an Impala with the 5.3 engine reports highway mileage of 20.5 MPG. Another reports 19.5, but some trips are more (23). Owners with V6s are getting around 25 MPG.

I drove thru Chicago recently. Yes some people were speeding, but I found that the traffic was moving at about 60 MPH, not 80 MPH. I tried to stay out of the way of the speeders. I doubt that the speeders were really getting whereever they were going that much faster.
My experience is that speeding along at 90 MPH does not really save that much time by the end of the day. This is because you will end up clogged in slower traffic a lot of the time. In Wyoming traffic clogs are less frequent, but most highways are two lane, so you will get behind a truck before long...

According to the computer I got 69 mpg in a '98 Deville about ten minutes ago, so I think the computer is full of bantha poodoo.

I can get an instant reading of 70 MPG going down hill. Even better though, driving my 98 Aurora into Death Valley from the west, the range for what was left in the fuel tank went up to 999 miles. The fuel tank only held 18 gallons full....
