The major problem is that they are not spotting the weak points and they are not fixing them. I am comforted by Musk's identification of communications problems as a major issue last month, but his proposed solution ("just call people directly across the hierarchy") is stupid and betrays a lack of understanding of the nature of the problem. Also, the communications problems have been serious since at least 2013, they've been getting only worse, and he's only *now* spotted the weak point? I hope Tesla gets to the point where they are identifying the weak points and fixing them on the fly. They seem to be doing so in manufacturing, and in hardware... not so much in software... really not at all in communications.
