No. Rear-view cameras are safety. They're simply a switch. IF in R turn on CAMERA. If move to D, turn off Camera. If MT, IF in R, Camera, if not no Camera. Gas

Gas mileage is simply an op-ex of a car, and does not make more "sense" over a rear view camera, because increased c pillars decrease overall glass and visibility. I rather pay a few bucks more in gas then have a featureset unused in my car or have to go through disabling it every time I operate it.
