It is embarrassing to have released cars year after year with fundamental problems that have not been fixed, year after year. Or, it should be. American carmakers really should be embarrassed.
We do not know if next year's car will actually be notably, or even any, better than this year's. The article says they hope so, but obviously nobody knows. Probably there will be fewer of a class of bugs in the new code, but there might also be radically less code implementing needed features. We can only wait and see.
