Been thinking about all those airbag recalls. Seems like manufacturing anything is pretty hard, and when they are as complicated as cars, the actual effort of making that many of something so complex is pretty impressive...as long as the quality is good. It seems like Tesla has been raising the bar for pretty much everything in the auto industry, but are they doing anything new in quality control? I know it's boring, but it's critical, any thoughts? My only thoughts are 1) they are probably automating things more than other manufacturers so that helps and 2) since the cars can constantly send feedback that probably helps too.
