Production of the Tesla Model S is now exceeding a rate of 400 units per week.

That's a known.

What's unknown is what it took for Tesla to get there.

Why now?

Were there production hiccups along the way?

What's next?

And what's that far-off goal?

Bloomberg recently fielded these questions and, in doing so, provided us with some decent answers.

How's 500,000 units annually sound?  Some day that might be where Tesla stands.  Do you believe that?
