Does anything about this thread really surprise you though? As to be unbelievable? Do you think that other car manufacturers are that much better? I've read so many insane stories about software in Toyotas (or was it Honda?), and those are very old, very well established companies. That a company like Tesla would have rock solid software would be a miracle.
Didn't we just have this yesterday, with the junior shocked to find that code in the real world doesn't at all look like the ruby "made with heart in Portland" stuff that has all the stars on GitHub?
This is what systems look like in every industry. Look no further than the crappy Java SWT GUIs you see in those leaked abhorrent NSA powerpoints.
