Do you have a source on this? I am aware the auto industry is highly automated and robots outperform humans at a lot of the manual labor, but the word "partially" is hand-waving away a lot of big shifts in industrial engineering and national regulations. It just seems difficult to disentangle. (E.g. it is difficult for shops to automate until they get their systems in logistical order, and a low-regulation environment might encourage a race-to-the-bottom of pushing cheap robots way too hard and ignoring QC failures.)
