I'll admit that I average under 70 MPH in my 2010 Ford Fusion hybrid highway driving but I do get over 42 MPG highway. Just how many places is 75 MPH legal or within 5 MPH? Not in the Northeast where we don't have enough 65 MPH highways.

There's a reason President Carter lowered the speed limit to 55 MPH.

75 is quite common west of the Mississippi. In general though, the closer one is to urban centers the lower the maximum speed limit is.
Highways in and immediately surrounding Los Angeles, for instance, have 55-65 mph limits. Get 40-50 miles or so away and they increase to 75- I10 and I15 for example.

That was actually enacted under Nixon.

19% under the EPA rating is very consistent with other gasoline vehicles. Diesels, on the other hand, tend to do around 18% better than the EPA ratings.

I get a steady 38-40 mpg w/2000 Echo 1.5 liter by driving sensibly, but since Ford is advertising to idiots who think they can go fast with no penalty, they should say so. Variable cam timing is so cool. So is light weight.
