Was just about to post this, glad someone else did.
I have a car with both (birds eye view and parking sensors), and they are absolutely complimentary to each other, and I use them for different reasons. E.g. for squeezing through my garage door (I only have about 1.5 inch of clearance on each side) I like the birds eye view, but then when I pull up to the front of the garage I use the sensor because I know exactly how many inches from the front my car should be so that I can both walk around the front and the back if I need to unload stuff from the trunk.
By opening the door to the living room, opening the car door in the free space that has been cleared by opening the living room door. easy peasy : https://www.youtube.com/watch?v=3-MaC9fFtz0
