Golf ball cars

Main Question or Discussion Point

This is my first post on this site and I figured I would maybe get a good answer to this question. If the dimples on a golf ball are to reduce the amount of friction due to air resistance, why don't car manufacturers dimple the sheet metal on their cars to reduce coefficient drag?? Just wondering.

I believe Lexus is now doing it to the underside of one of it's vehicles. Since the vehicle is not spinning, I would think there would not be a need to dimple the entire surface of the vehicle, just where the aspect of a negative pressure gradient would want to cause seperation of the BL (the rear side of the car). The dimpling would not be a good idea on the entire car for a couple of reasons I can think of:

1) Manufacturability would decrease i.e. it would be harder to make them.
2) The asthetics of the vehicle would be horrendous. The vehicle has to loog good or it won't sell.
