Apart from aesthetics, I don't understand the whole not wanting a front number plate thing. It doesn't affect aerodynamics and helps in identifying drivers doing the wrong thing. What's wrong with that?
Reference on a the aerodynamics not being effected? Im not an aerodynamicist [but I do like to hold my hand out of the car and pretend it is an airplane] but I'm not sure how bolting a box onto the front of a car would go unnoticed by the laws of nature.
