i just thought about this driving down the road, and some jack azz was behind me, do they make the speed limit, just to protect you from driving to fast and wrecking, or does it actually save you gas also?

In theory the speed limit is the maximum you may go for safety sake.
The slower you drive the better gas mileage you will get. I drive a 2005 Chevy p/u. at 72 miles per hour I get 17 MPG. At 68 MPH I get 21 MPG so I set the cruise control at 68MPH when ever I can for the better gas mileage.

Oddly enough 55 was determined to be the optimal speed limit for gas efficiency, so back in the day when there were gas shortages, that's when a lot of the speed limits became 55.

They really don't prevent you from driving fast (just ask the millions of people with speeding tickets) but they are allegedy there with safety in mind (although you can just as easily be injured at 35 as you can be at 55). You and I both know that driving 55 will save you more gas than driving 80 (and yes, I am speaking from experience).

I think they make speed limits and other highway laws to protect people from accidents. The gas comsumption is just a secondary benefit of not speeding. Especially in times when gas is some damn expense.

its to keep down the speed so that there is less risk of having an accident with anyone else on the road, but also it would save on gas as going at a lower constant rate is better than erratic acceleration and using more gas that way.

Where I live it seems that the speed limit is just a suggestion that no one really follows!!!
Which is more important getting good gas mileage or not getting run over by faster vehicles??

Slow Down! According to the Car Care Council, there is an aerodynamic drag on your car that at 70 mph is double the drag then at 50 mph. slowing down can increase your mileage. Each mph driven over 60 will result in an additional 10 cents per gallon down the fuel tank.

it does both Michigan had a energy speed law before the speed limits went back up. if you were going faster than the posted speed but slower than the old speed you got a different ticket

Both actually, it gives you ideal mileage in all cars for that road. Also, they make that specific limit for the turns and twists on the road so you can keep control of your car.
