> Safety is extremely important, so you expect some slowness as a result, but it got pretty extreme. I remember one time having to do 6 weeks of testing around a one-line code change because a "helpful" dev fixed a small bug that had no practical impact.
Not to bring Tesla into this, but the contrast here is stunning. From a component manufacturer about the mindset of Tesla:
"Hey, we sent you over the new firmware for the component, check it out." (The test suite for this component takes approximately 36 hours to execute.)
Three hours later:
"This is working so much better, thanks a lot!"
"???"
"Oh, we just flashed a car we have here and took it out for a drive."
