"That's our focus right now".
When asked by an analyst on a conference call about all-important reservations for the Model 3, Musk cut him off, calling questions dry and "not cool".
He then took several questions in a row about plans for a self-driving vehicle network and other long-term projects from the host of a YouTube channel focused on investing, praising the questions as not boring.
The adjusted loss per share was US$3.35, against expectations of US$3.42 on a revenue of US$3.32 billion.
To achieve those Model 3 production numbers, Tesla will shut down its line again this quarter to make modifications, according Mr Musk. Through the vast majority of Model 3 production, including in body welding, general assembly, inverter and drive unit production, our automation effort has been very successful.

Tesla faces a crucial time in its 15-year history, with the company under the gun to show it can efficiently and profitably build its first vehicle intended at high volume.

Tesla's future depends on the Model 3 and the company said that it had largely overcome production bottlenecks, with Musk vowing a dramatic turnaround that would reverse losses and generate positive cash flow in just a few months.
The Model 3 starts at $35,000 (£25,700) but with options can easily cost more than $50,000 (£36,800).
Shares of the Palo Alto, California-based company were unchanged in extended trading after closing at $301.15. "We're going to scrub barnacles on that front", he said.
"We have temporarily dialed back automation and introduced certain semi-automated or manual processes while we work to eventually have full automation take back over", the company said.
Tesla burned through $700 million in cash last quarter, but its production woes appear to be easing. It previously forecast spending of at least $3.4 billion.
The giant loss in a critical quarter for the 15-year-old company was bigger than Wall Street expected. The lowest sales estimate is $2.92 billion and the highest is $3.52 billion. The company ended the quarter with a cash balance of $2.67 billion.
In March, Moody's Investors Service downgraded Tesla's debt. At the end of a year ago the company had a total of $9.5 billion in long-term debt.

Musk said the company is also working on reducing its spending this year and Tesla expects to spend less than $3 billion on capital expenses this year, compared to $3.4 billion in 2017.
It all comes down to one thing - the Tesla Model 3.
