Just wondering about the ladies on this forum. Are the rear backup sensors sufficient, or is the rear camera absolutely necessary? Also, would bigger mirrors help? I hope GM seriously finds ways to make it easier to backup up...My wife has warmed up to the idea of an Acadia/Outlook, so when I'm ready to test drive (considering buying in 18 months) I hope this issue would be worked out. GM should just offer the camera as a stand-alone option.
