Because it's a variation on the Bolt, which isn't designed to accomodate that. GM and most other OEM's have a variety of concepts for vehicles designed as robotaxis from the ground up, but they're all several years out. Although the busses in my city don't have rear facing seats either, they exasperate motion sickness in some people. Zoox is building a bi-directional robotaxi that has no front or rear, it goes both ways the same. All four wheels have independent steering and motors. It would be too weird for a human to control manually at all.
