Here's an idea - take the Robocab car design, strip out all the FSD/autopilot stuff, put in a steering wheel and dash and sell it starting at the end of the year for ~$25k. It would sell +++
It has no rear window and wacky doors and only two seats. It would not sell. It's purpose built as an autonomous taxi, where those choices make perfect sense. They are also doing a $25k car, they just aren't revealing it today.
I believe the reason was it adds strength that let's you have higher wider glass roof above passengers heads.
And the rear view mirror replacement uses cameras.
