Tesla's mission statement is over a decade old. Rather than pontificating, provide some examples of them not adhering to this statement.There's really two questions here:
Why would Tesla give up what appears to be a competitive advantage w/it's charging network exclusivity?
And why VW Group be so negligent with it's charging network when it seems as if there's so much to be gained by doing it right?
In both cases, we can be certain the respective organizations are making their decisions, doing (or not doing) things, for the sake of long-term profitability. They are not doing them for any kind of altruistic reasons.
So I think we'll eventually learn it's much more about strategy, about long term planning, than anything else. I'd be highly skeptical of all PR statements from both organizations on the subject. It's not like they're going to draw a fully honest roadmap of their long range plans for their competitors to see.
As for VW, they're clearly doing the absolute minimum with EA so not to incur further fines for diesel gate.
You may think your fooling us as the "cynical genius". Maybe you're just not that bright:
