Earlier quoted context omitted.
"Ability to make turns is a non-goal for the MVP of the car we're building" You can't record a cover of Queen's We Are The Champions or Somebody To Love without struggling with the UI if 3/4 is not supported. Or Blondie's Call Me. Or a plethora of other popular music. "Fully Featured (in our imagination)"
"Including a rear parking sensor is a non-goal for the MVP of the car we're building" seems to be a closer analogy. If you cannot use the MVP of the software for your use cases, that doesn't mean it cannot be worthwhile for anyone else.
The rule of thumb is that you need to design to support at least 3 different use cases from the start if you want to create something that can viably extend to being a generic product.
