FUD, FUD, and more FUD.
First, NTSB has no authority to "ban" Autopilot. This is an outright lie on your part. They are an investigative body that can issue recommendations:

Second, Autopilot is a distinct option from Full Self Driving. Almost every driver assist system available to customers today uses only Radar and Cameras. It is highly unlikely that Autopilot would be "refunded". Whether FSD can be accomplished without LIDAR is still up for debate. Your assertion is misleading.
Third, there does not appear to be any "lack of demand" for existing Tesla products:
"Tesla confirmed to Business Insider that the Model S and X delays are due to an increase in demand for the vehicles rather than production difficulties. That's surprising, as some thought the Model 3, Tesla's most affordable car to date, would cannibalize sales of the S and X." - Tesla is pushing back Model S and Model X delivery dates — but that may actually be a good sign for the company
Mode S, Model X, and Model 3 serve different product segments.
Cash flow and operating capital are legitimate concerns, but until the Q1 report, nobody will know the current situation or trends.
There is a difference between bringing up legitimate concerns, and trying to gin up fear through misinformation and insinuation.
