I once saw a patent on that already earlier somewhere, which i assumed was the reason none of the automotive navigation UI's where doing this.

Just checked again, and it's verbatim this use case and even active until 2030 still:

3-D map display

Abstract

A computer generated 3-dimensional map display includes a reference icon identifying an observation point in the geographic area defined by the map, the map being presented on a curved surface which extends from a first plane to a second plane which is substantially orthogonal to the first plane. The observation point is located in the first plane. The display is configured such that the height of landmarks and buildings in a defined foreground of the reference icon are presented normal to the first plane, the height of land marks and buildings at a defined far distance are presented normal to the second plane and the height of land marks and buildings in a defined middle ground are presented normal to the non-linear portion of the curved surface. The geographic area represented can be translated along the curved surface to provide a perception that the reference icon is roaming through the displayed geographic area.

By no other than "Here and There" Schulze and Webb Ltd later rebranded to BERG.

The generic use case of a multiperspective camera method for that was arguable covered in a 1997 Disney paper latest.
