I once worked for a big corporation that makes hydraulic rescue tools, where management somehow failed to grasp that the chief selling point of these tools is that they do the job reliably every time. No firefighter wants to be trying to get someone out of a car like, "Damnit! The cutter is acting up again. We should probably look into that."
But the executives kept demanding that we add "features" to the tools that effectively compromised the reliability and then got all surprised Pikachu face when it was explained to them that the customers thought the tools were overpriced half-assed garbage.
I guess my point is I've seen plenty of incredibly stupid examples of management ignoring the engineers and yet somehow Musk demanding that radar be scrapped in favor of cameras is right at the top of the list. Especially if you want your customers to live long enough to buy your products more than once.
The Book of Mormon is a wild ride.
