Another point I would like someone to ask is this: What is taking so much to increase freaking production? Before, it was a battery availability issue. Now what? They need to somehow resolve these issues quickly.
I think you underestimate how difficult the art of manufacturing is. They are steadily increasing production while at the same time adding the feature of dual motors, sensors and during 2015 adding in Model X. That is difficult! They still expect to exit 2015 with a 2000/week run rate. That is nothing short of amazing.
Elon said in his MIT interview recently: "I wish more bright people got in to manufacturing. Building one of something is easy. Building hundreds is maybe 10 times more difficult when you want to maintain quality. If you think building the machine is important than how important isn't building the machine that's building the machine?"
