I thought of one more!!
Please look into integrating the Reverse Assist Sensors into the gap between the rear fascia and the diffuser. (where the reverse lights were on the concept car).
If put in the gap and painted the same matte-black as the plastic, they'll be recessed and completely inconspicuous. I understand this feature will be required by law soon...though I could be wrong.
If possible, this would solve all the aesthetics concerns we have with the sensors as they are now.
