At that time, Tesla's market cap was $30 billion, ridiculous by any measure. Last week it popped to over $50 billion and passed General Motors in the total value of its stock.

Still ridiculous, still resembles a tulip bulb that is valued at more than the ship that delivered it.
Maybe our markets are just not that efficient at times.
As Lee points out in passing along this article, http://www.nationalreview.com/
That $176 billion is about $2,200 for every family of four in this country. Every last man, woman, child, transsexual, illegal/undocumented immigrant and politician out there. The info is hard to come by, but that amount is about half the estimated losses in the subprime mortgage crisis, but the total effect on the economy was the loss of value/wealth in the $30 trillion range.
Since we are just about out of things to worry about, worry about wind energy subsidies, the failure of all those loans/loan guarantees and the fallout that happens when that type of thing ripples through the economy. Oh, and don't forget when Tesla's stock falls back to earth...or the dark side of the moon.
