simple as:
“You should NEVER see your car.”
Official guidance actually describes more than one approach.
The U.S. National Highway Traffic Safety Administration’s current guidance says that a traditional mirror setup has the outside mirrors adjusted so the sides of the vehicle are just visible. It also describes an “enhanced” setup in which the mirrors are turned farther outward to reduce the blind areas alongside the vehicle.
AAA similarly recommends positioning each side mirror so you can just barely see the side of the vehicle, using specific head positions
