Quite possible. Things that are designed for robotic assembly turn out to be fabulous for human assembly.
Remember the old IBM Pro-printer? It was assembled on a fully flexible robotic line. When demand exceeded the line capacity, they installed a temporary human assembly line. The human line output was 4 times greater than they had expected. Humans are amazing.
I dont know how true it is but I read somewhere musk had assembly line robots removed and replaced with human labor.
Youre correct. Reason being, the car is a kludge. Parts and sub-assemblies have to be hand fitted and jiggered till they fit. Even with this Fit/Form/Finish sucks and would be laughable if that poor quality of product should be put out be any of the majors.
