I don't get involved in the throttle stop argument, probably not highly accurate but even if the numbers are out by +/-10% it is still a useful technique.
What about sailing, cars can be designed to get some thrust from crosswinds.

Is it ridiculous to envision some pop up roof sail or wheel fairings that reduce the effect of the crosswind? Or maybe a wheel fairing like the Daihatsu UFE, maybe road cars are too big, with too wide wheels etc.
