Having a backup camera installed in vehicles became mandatory in May of 2018. While this is a nifty feature, not all cameras -- or displays -- are created equal. I've seen some pop up in a 4-inch rectangle on the rearview mirror, and I've seen others, such as the one in the 2020 Genesis G70 give multiple, selectable views on a big center screen.
I wouldn't recommend that anyone drive by the camera display alone, but this is a nice tool for fine tuning your parking job. The top-down view is especially helpful in tight urban spaces when you are trying to maneuver around parked cars, curbs and potholes.
Unfortunately, though backup cameras are standard, sexy birds-eye view displays are usually optional content. For example, on the G70, the surround view monitor is available on the base vehicle, but you have to add the $8,450 Prestige Package to get it, which will put the vehicle price at around $45K.
