Reply to comment by Flaxmoore in TIL about The “Victory Speed”. Beginning in May of 1942 and ending in August of 1945, a nationwide speed limit of 35 miles per hour was instated. The “Victory Speed” limit was instated in order to reduce gasoline and rubber consumption. by Phillip_Lipton

The fact that modern cars aren't more thoroughly streamlined is still silly to me.

Give me a giant pill, man. Screw the aesthetics.

And it takes very little to change the efficiency.

I had a car bra for my 3 series- E36, the last of the boxier models- and with nothing more than smoothing out the bumper/fender transition and adding a couple small wedges to direct air a little I got a full mile per gallon highway improvement.

That's over a full summer of testing, with the same drives done over 50 times. Held up nicely- 30mpg highway without it, 31 with.
