I'm not much of a sailor but...

Several friends that are avid sailors pointed out that, with the right shape, a good side-wind can actually make the car more slippery due to the sail effect.

A good airfoil shape also has this tendency up to the point of stall. So, in this case making the tail longer actually helps....

And again, the above only works for low angles of yaw. These designs are always a compromise.

If the wind is coming at you at 90, then you have more losses due to the larger surface area.
