No wait, I'm serious... I wonder if Tesla will take a leaf from the Sirius Cybernetics Corporation's book and install a Genuine People Personality feature? Uncanny Valley represents a huge gulf (
https://en.wikipedia.org/wiki/Uncanny_valley). The creepiest feature of Lovecraft's Night-Gaunts (at least to him) was that they have no faces. We try to bridge the gap with jokes (e.g., google drunk northern Atlas), but domestic consumer uptake is going to depend on manufacturers seriously taking it into account.
There is (I kid you not) a field called 'cute studies' aimed at determining how consumers will accept potentially disturbing technology when it's presented in a welcoming form. Japanese designers particularly have taken this on board. With a rapidly ageing population and resistance to immigration, they anticipate that the elderly will require a lot of robotic caregivers and since many will have Alzheimer's, they have to be as nonthreatening as possible in their appearance and manner.
As Mori found with his research on the uncanny, close-to-human-but-not-human really creeps people out. Design and presentation will have to be somewhat toy-like or cartoonish for caregiver robots. Large, expressive 'eyes' (not necessarily functional as optical receptors) will probably be an essential (static, glassy, 'dead' eyes most definitely will not be).
I think that Tesla is going to have to do a lot of market research to see if general consumers will welcome this. Maybe the techniques used in game design - the behaviour of non-player characters - will provide an inspiration. Maybe a design that's more deliberately cool than cute - younger generations may accept robots more easily than their elders.
While Douglas Adams' intention was satirical, Marvin turned out to be an immensely popular character (in the radio series and books at least). If they didn't find him grating, people felt a bond of sympathy with him.
