Using more resource than necessary to build a product doesn't it has deficiencies from the user point of view.

  But they admit it's not just a matter of resources, the quality is changing: "Model 3 quality is rapidly getting better". That means Tesla itself is admitting there are some Model 3s out there better than others, pretty wild for a new car.

    > pretty wild for a new car This is the heart of the question. My understanding is that Tesla Motors, unlike most every other car maker, iterating their manufacturing (hardware) side as quickly as they are iterating on the software side. For a more concrete example, the initial version of the SpaceX Merlin engine had 76,000 pounds of thrust. That same engine now has 205,000 pounds. I saw an interview last week where an employee at SpaceX said that no two Falcon 9 rockets come off the line exactly the same. Iterative hardware improvements are going on all the time. This is unheard of in aerospace. This is a huge advantage compared to traditional manufacturing approaches.

      How can they be certain the improvements don't have side effects or downsides. If every iteration of software is an improvement, we would have bug free software!

        Applying considered and appropriate effort to anything will tend to improve the thing. Its why we have smart phones and cities today. It's not an absolute; I've seen good software lose its quality with inappropriate and ill-considered effort put into it, but that's not the norm. More concretely, each of the previous three Tesla car models have improved steadily over the years.
