Essay: Variable Degrees of Translucency

Car door panels and fenders are generally made of steel, sometimes of aluminum or plastic composites, and you can't see through them. Car windows, on the other hand, are made of a transparent sandwich of glass and plastic - and you can see through them.

Aerodynamic efficiency is clearly paramount.
