Why mfg is a SKILL
This is why manufacturing is a SKILL that can't be picked up in a few weeks.
Front seat of a Tesla less than one year old.
A couple of handy comparisons from items I happened to be reading today:
Front seat of a 1963 Chevy Nova, used steadily for 56 years.
Front seat of a 1967 Ford truck, used steadily for 52 years.
All three seats are plastic. Chevy and Ford know how to select and test materials, and how to watch for consistency. Tesla just bought cheap.
(For fairness: Those pix are atypical. Most 50-year-old car seats are cracked and busted, but they weren't cracked and busted in the
first year like the Tesla seat.)
