Following the call, we stated:

Regarding Model 3 production bottlenecks, battery module production is still the focus for near-term improvements. A new automated system for two of the four zones is nearing completion in Germany. It needs to be disassembled, shipped, then reassembled at the Gigafactory (it's expected to arrive in March). This one line should be as productive as three to four of the lines they currently have and take up less physical space. They also have a "semi-automatic" line, which involves people working with the machines. It has been, Musk said, "remarkably effective," and is exceeding the purely automatic lines.

Automation is key for several reasons. First, as stated above, production will increase as the level of automation expands. But there's another, more important aspect to this. It was mentioned during the call:

"This is the year when we believe we can achieve true cost parity – producing a premium EV like the Model 3 will be no more expensive than producing an ICE vehicle, something that many believe is not yet possible."
