Move fast and break things that move fast…

I don’t really like or trust most (if not all) of the established automakers, but there is something to be said for having several decades (over a century in some cases) of experience building potential killing machines vs. a company that’s not even 15 years old. The established players have put out cars which suffered freak malfunctions, but Rivian (and Tesla) seem to be struggling more with QA.

Non-rhetorical question: do companies have safeguards for critical components like braking systems, or are they also prone to catastrophic failure if a software engineer pushes a bad commit?
