Wall Street analysts have been saying for months that the company would need to raise more money to sustain a ramp up of production of the crucial Model 3 sedan, but several said on Thursday that might no longer be necessary.
A Tesla spokesperson confirmed the company had received a "voluntary request" earlier this year from the US Department of Justice about its "public guidance for the Model 3 ramp" and cooperated with the request.
But the major difference between the three service is that Musk's platform, dubbed the Tesla Network, would be entirely made up of autonomous cars.
The automaker has previously warned that production capacity in its Fremont factory is essentially maxed out, requiring a temporary structure to support the current volume of Model 3 output.
Musk later abandoned his plan and the Securities and Exchange Commission subsequently filed a lawsuit alleging that he had misled investors because he was never close to lining up the estimated $25 billion to $50 billion that it would have taken to pull of the deal he envisioned.

A third suspicious package was found in the mailroom of the Time Warner building in New York City, where CNN has offices. White House spokeswoman Sarah Huckabee Sanders tweeted that President Trump was monitoring the situation closely.

Company looking to expand Model 3 production. We are enormously proud of the efforts of the whole company in making it through this hard ramp and getting us to volume production. He remains CEO but is stepping down as chairman of the board and bringing on two new board members.
The usually freewheeling Musk was unusually restrained through most of the call with analysts, although he occasional broke into some braggadocio.
While the third-quarter results were definitely "impressive", and spurred at least one upgrade to outperform at Wolfe Research, most analysts questioned whether the profit and robust cash flow were sustainable and can be repeated next quarter.
Musk, 47, made earlier predictions related to the Model 3 that were even more outlandish than the ones he gave a year ago. The Company reported an adjusted earnings per share of Dollars 2.90, increasing from a loss of USD 2.92 per share previous year and smashing analysts' estimates of an earnings per share loss of 19 cents.
