And as now Tesla has moved past that early 'greenfielding' stage, their situation has changed to be dramatically more similar to the 'legacy' car makers. And suddenly, Tesla sees that their supposedly superior quirky approaches to carmaking generally are probably going to 'solidify' into systems eerily similar to the legacy ones.
Whoever was dismissive of the legacy car makers was also assuming decades of innovations in maintainability planning and reuse logic in one of the most highly competitive industries. Turns out, Tesla - even though the shook up the legacy contenders early on - is losing a lot of the advantages quicker that they have imagined to stay. Hardly a surprise to anyone who understands that millions of highly skilled engineers in the car industries aren't exactly less competent than the average Tesla engineer.
