Human spaces are built for humans. Outdoors cars and quad coppers are a great form but constrained by stars, doors, and low ceiling makes them a poor fit.

Alternatively a 2 foot tall or a 20 foot tall humanoid robots aren’t particularly useful. But a good enough 5-6 foot tall humanoid robot can be swapped into an assembly line wherever a human is currently working without redesigning that workspace.
