All cars nowadays go thru wind tunnel testing and that bevels any styling the car may have had. BTW that smoothing out only adds about .5 MPG to the cars fuel economy, but hey who am i to complain..
There’s a me-too thing going on above and beyond aerodynamics, though. The Ford Fusion set off a series of imitators, from Hyundai to Subaru, same profile, same front grille, similar headlights and taillights. It’s possible to be aerodynamic and not look like everything else.
Considering all the other factors that affect gas mileage that has to be a ridiculous policy.
Which makes me suspect it could have something to do with the EPA or some other foul nest of bureaucratic busybodies.
