Most people who understand how difficult it is to produce a new line of cars, or have been listening closely to what Elon has been saying pretty much expected that ramping up production would be hard and Tesla would miss their goals many times. Tesla has never delivered a car on time. But there is enormous demand for this car and they will eventually make it work. At the current run rate they are already able to produce around 100,000 Model 3 per year, and are ramping up quickly
This will become a problem if they run out of cash. Not delivering as many cars as planned is fine if you make a profit (or at least positive cash flow). But burning more cash than expected can be problematic. Especially if you constantly miss deadlines which means investors don't know if they should believe any of your plans.
The second issue is that of competition. Model S didn't have any meaningful EV competition. Model 3 competition is still comparably low but this will look different in 2-3 years. If they produce enough cars until then, prospective buyers will eventually switch to another brand.
Does he still have that much cash? Would expect that SpaceX would have to cut if Tesla really needs money. I don't think Musk has much cash lying around that's not already in one of his companies.
Enough people believe in Tesla that they can certainly find a way to generate cash. As a WORST case scenario i’m sure another auto maker would love to recapitalize them in order to acquire their technology. Tesla actually going out of existence seems unlikely to me at this point.
This is why I don't think it's a very big problem for Tesla. There is a big difference between not delivering (so far Magic Leap for example) and slow delivery.
Most people who ordered a Tesla realy want one so they are just going to wait.
Maybe some shareholderd might see it as a problem because they could have sold more Teslas in the same amount of time. But it's not that they are cheap and everyone can afford one.
One of those things doesn't sound much like the other.
