35 years in Materials Engineering, Financial Warranty Recovery, Module Leader Transmission and Drivelines, Hew Model Launch Co Ordinator, and development of various cars from mini, various saloons and estates, 4x4s and very expensive hand built sports cars.
We did teardowns if many competitors cars including Teslas and Toyotas I have visited many car manufacturing plants, including Toyota City, Honda, Mazda, Nissan in Japan, Ford in Dearborbe and various German plants.
Toyota are nit at tge forefront of manufacturing,rather, like the corrola, find a process that works and sticks with ut. They failed to see the push towards evs and have been rushing to catch up.
I will say again, the reason Teslas are so expensive to repair us because of poor engineering design.
