Yes, it sounds very cool and sci-fi, but having a humanoid control the car seems less safe than having the spinning cameras and other sensors that are missing from older cars or those that weren't specifically built to be self-driving. I suppose this is why even human drivers are assisted by automatic emergency braking.

I am more leaning into the idea that an efficient self-driving car wouldn't even need to have a steering wheel, pedals, or thin pillars to help the passengers see the outside environment or be seen by pedestrians.

The way this ties back to the computer use models is that a lot of webpages have stuff designed for humans would make it difficult for a model to navigate them well. I think this was the goal of the "semantic web".
