*The ABS thermo-formed sheeting has no structural rigidity by itself and would flap like a bed sheet on a clothes line without some sort of corrugation to stiffen it.
*The automakers appear to be borrowing from 'real' racing diffusers to create a styling cue gimmick with a low cost cheap plastic part which can be changed each year like a woman's handbag, along with the car's front fascia, which changes each year as well; so a buyer will feel like their 'new' car is actually 'different' from the previous year model.
*Carr's wind tunnel research showed zero requirement for strakes to be included on a diffuser in order to ensure it's performance for fuel economy.
*Racing diffusers are for downforce/high-speed stability.
