Why don't we have special cycle clothing, with a zipper on the back of your jacket that you can open, which opens up a very large, area where the wind can blow in (when you have wind in your back), thus partly blowing up the back of your jacket so that it acts like sail. I think you can go 5-10 km/h faster when the wind is in your direction. Something could also possibly be designed for side-back winds so you still get a small advantage.
