GasPods. (chuckle) That's bloody brilliant. I'll go one better. Tape some bratworst sausages cut lengthwise to the cab. It it doesn't work, you can eat them.
And here's the reverse: I once saw a guy with a huge lifted truck running down the interstate with a two foot long loop of logging chain and two huge hex nuts the size of which might be use to bolt a bridge or an oil rig together swinging from his trailer hitch which was something like four or five feet off the ground. I imagine that nobody would ever tailgate him him because of all of the heavy steel he had in motion back there. Probably cost him a mile per gallon because nobody would draft him.
