That may have been the case 5 years ago, but these days it’s the opposite. Look at the Munro live Tesla tear downs on YouTube, particularly the megacastings structure, the battery packs or heat pumps. It’s night and day.
My point still stands and it clearly shows that Tesla have room to improve, just like all car companies.
