It is semi-autonomous driving software, so the use cases are what you might expect. For example, I have seen many Youtube videos where people are using it for supervised semi-autonomous drives. Some say that once you're used to its quirks, it's less stressful/easier to drive this way.
In the end, who knows? Who cares? If a customer says they are happy with the purchase, why should someone else tell them they are plain wrong? I can disagree, of course, but I should not tell them they're just wrong for being happy.
I don't tell people they're wrong for paying extra for a special paint color.
