Yes, and as we proved before, the 55mph speed limit more than used up the fuel savings in damage to our economy in terms of lost time.

FYI, my *older* car gets better fuel economy at 75 than it does at 55, due to gearing and powerband. A lot of other cars are that way too.

That argument was made by those who are in the long haul trucking industry, which continues to have the 55 speed limit imposed on them. Sorry, try again.

That simply cannot be true. Air drag increases with the cube of the velocity. Older cars were rarely designed to reduce drag.

I can set the Cruise on my 94 Roadmaster on 75 and get 26 MPG all day long. Not bad for a big car with a big V-8, I doubt many new Impala’s with 6 cylinders do better.

Let's see. According to the US Dep't of Transportation, the average commute in the US in 1995 (old data, I know, but the most current I could find) is 11.6 miles. 11.6 miles at 55 mph = 12.6 minute commute. 11.6 miles at 70mph = 9.9 minute commute. minutes.

Is that two minutes and forty-five seconds each way *really* destroying the economy? I doubt it.

Oh - source for the USDOT info is here.
