Car analogies are very good. If I buy a car, I expect it to drive nicely. Surely I don’t want it to freeze and turn off itself suddenly here and there. Probably they make them reliable, because they know there will be no chance for bug fixes. If there are bugs in a car, the whole series will get a bad name, probably the whole company too, and they will be soon out of business. But if cars could be updated with bug fixes, then I bet they would be half reliable too, just as software.
