I don't think so. The question is of 'fineness ratio'. The best example of crosswind performance may be Morelli's Banana car.
Thinking along that line led me to this one, on the left:
A truncated boattail with Coanda nozzles, fed engine cooling air. The nozzles configuration causes the air to follow the curve to the vehicle centerline. Sort of a space warp.
The nice thing about Coanda nozzles is if you can sense crosswinds and choke the nozzle on the downwind side, you can steer the streamlines side to side. This is getting a ways from the Template.
