The big danger with buying a Tesla isn’t so much that the company will go under as much as it is that if the company goes under, every Tesla on the road today could get permanently disabled via software update by the company or its creditors as a way of reducing future liabilities.
I will never understand why people do software updates. They always suck more than just running the original version till it dies. A software update should pretty much be invisible to the user, instead every software update I ever get changes the way many things look and function.
