Completely disagree. Tesla is, I think, unquestionably the most impactful company in the game, including GE and Nissan. For two reasons.
First, before Tesla people thought of electric vehicles as ridiculous DIY golf carts driven by treehuggers. They were utterly uncool and stupid. Post-Tesla, electric cars are among the very coolest cars in the world. GE didn't do that. Nissan didn't do that. Toyota didn't do that. Tesla did. I think fundamentally changing people's perceptions of what an electric car is and what it can do is the single most impactful action in the industry so far.
Second, Tesla's critical product isn't their cars. Their critical product is their battery technology. It is second to none, in a business where the battery is everything. This is the reason that both Daimler and Toyota have invested in the company. I think you are seriously underestimating how important this is.
As to the article proper: it seems to me that running down your car is a pretty simple problem to engineer away. This might be an issue, perhaps a burp that Tesla has to get fixed pronto. But it's hardly, to use the breathless headline, devastating.
