Could the Y ramp be yet another bet the company near disaster? The possibility can't be ruled out. However there are many good reasons that Y ramp problems (of course there will be plenty) are very unlikely to threaten the company's solvency.
First, instead of operating cash from only S and X (and cash reserves) supporting the build out of manufacturing lines designed to triple annual production, the Y ramp's build cash will be supported by cash generated each quarter by S, X and 3 sales. Even if the Y ramp bled cash at the same rate as 3, that could be sustained for as long as needed.
Second, the Grohman acquisition integration with Tesla engineering is much, much further along now than it was in 2017.
The single biggest mistake in the 3 ramp was using an outside firm to build key portions of the battery pack lines. I don't imagine that lesson is going to be forgotten anytime soon. Tesla generally recognizes major mistakes and learns from them. Finding the next sweet spot between robotic tasks and ones people can still do better is another lesson. We can be certain they will again over reach on some automation, but they will have plans in place to correct more rapidly. Musk will set unrealistic targets as always, but the delays should be less and the financial risks from those delays will be less threatening.
