I view these things as pretty normal for the kind of company Tesla is. I know, Tesla is not labelled as a startup, but it kind of is one - if you consider it from the perspective of the sector it’s in.
The Chief Accounting Officer’s statement:
Since I joined Tesla on August 6th, the level of public attention placed on the company, as well as the pace within the company, have exceeded my expectations. As a result, this caused me to reconsider my future.
Especially the pace part sounds familiar. 
So, I take a long-term view on Tesla. It’s not getting everything right today. But that’s fine for me. I think it will do better. And I categorically support the renewables-based future it’s working on - even if that means short-term losses.
