Us as ecomodders try to streamline our cars so that we can cut through the air with as little resistance as possible. That is great and will always be helpful since we are moving our cars forward 99.78% (not real statistic) of the time. These modifications are extremely helpful when we are faced with a head wind, but if the wind is coming from any other direction they do us no good (other than fighting the resistance of our driving speed).
So, the question here is: Is there any way to take even greater advantage of side winds or tail winds, without negative effects?
I'm thinking something along the lines of reverse parachute.
