drees,I went back and re-watched the video.While the Ranger's mirrors don't "look" streamlined,they actually are,given their frontal area.
If you could get a look at Hucho's book you would find two separate reports addressing the streamlining of bluff bodies,Figure 4.99 and Fig.11.26.
Hucho uses the expression "saturation",where,once a certain degree of rounding of a leading edge is accomplished,the drag minimum is achieved,and no additional streamlining will affect a lower drag.
They're not "swoopy" but aerodynamically,they are very correct.
