    I don't get it...why not 55 mph?

    Because I can see my gas mileage moving up and down, I happened to notice something when I was driving on the Turnpike the other day.

    The speed limit on the Florida Turnpike is 70mph. I was doing 70 when someone pulled up on my bumper wanting to pass me but there were cars in the left lane. Since I find this personally offensive, I slowed down a little.

    At that point, I noticed a dramatic increase in gas mileage - from 36mpg to 44mpg (and no, he didn't hit me)!

    I would not consider myself an activist but I did write to the Governor of Florida asking him why he didn't reduce the speed limits to 55 mph on all state highways. I didn't receive an answer (naturally), but it seems like such a logical thing to do because...

    1. We would instantaneously reduce gas usage

    2. The State Troopers would help to increase the size of the State Treasuries by tons of money
    simply because people would have to pay more for their tickets.

    So...I don't get it. How come has thought about this, with or without congressional approval?

    If it is the instantaneous mileage reading that only occurs when you take your foot off the throttle, then you are only consuming the stored potential energy of the car, but that fades quickly, and then you have to once again overcome the friction, gravity and changes in road altitude. The marked change in fuel consumption was a fleeting event. Extrapolating your location by going "0" mph should provide unlimited fuel consumption which it kind of does as the engine will be off if you don't move but that takes away from the purpose of the vehicle.
