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.
Tesla quality is still lightyears behind old premium brands. Panel gaps so wide you could use them as kiddie pools.
Their scrap rates are testament of how crappy their production process is.
My point still stands and it clearly shows that Tesla have room to improve, just like all car companies.
