Cash-flow after investing activities is not really a thing, unless of course you are looking at companies from a VC-funded SV perspective. Just because you don't need additional cash-flow now doesn't mean you don't need it later. And positive cash-flow allows you to get additional loans, and re-pay those, when needed.

> "Not really, Tesla has $18 billion cash on hand and an established business model that works without opening up the chargers."

True, but building out the supercharger network is expensive and likely still a loss-leader for Tesla. Opening it means that Tesla can generate more revenue from an expensive asset.

> "Cash flow is not a particular concern for Tesla right now, they are cash-rich."

Cash flow is always a concern. Tesla would not stay "cash rich" for long without positive cashflow.

Their operating cash flow seems to be around 1.7bn $, based on the TTM column. Overall free cash-flow is 2.5bn $, repayment of debt alone is -16.1bn $. So if everything else fails, Telas liquidity goes strait out just for that. Throw in another roughly -16bn for investing, financing and capital. A solid position for sure when you have 16bn in cash in the bank. But none that would allow them to be generous with not using other cash-flow opportunities.
