This is true, but they issued all forms of debt already - shares, bonds, you name it.
Any further delays and they can literally go bankrupt.
And this is physical manufacturing do you can't ship beta and fix later for most things.
Also many have vested interests to see them fail - short traders, other car manufacturers, oil industry. I wouldn't rule out a simple sabotage - seems fairly low risk if it means oil industry can keep extracting profits for 10 years longer.
