Yeah but if they didn't change anything substantial and merely followed customer preferences and established norms, how would they justify the massive administrative and managerial bloat with inflated salaries in established auto companies? How will you keep the investor class satisfied without promises of massive returns within the next few years or so to keep that stock juiced with new gimmicks to sell? How do you keep the MBA holding c-suite relatives employed if they are simply making the same or similar bulk consumer cars for decades at a time? Think about that year or so window when only OEM parts are available to repair new vehicles before generic parts are modeled and built and the new and completely unnecessary tools that can be sold to mechanics and dealers that they can gouge people on.
