In order for that design to make sense in today's model 3, it would mean that very car is just a software update away from autonomy at "we are all watching netflix instead of looking outside" level. And that software update is coming very soon, in a matter of maximum 2-3 years.
I'm skeptical. I can very well see the next Model S, or the refreshed model 3 in 5 years achieve that [1], but really that's sacrificing today Model 3 user for something that's going to never be delivered to them. Not sure I like the approach of "this is a glimpse of the future that is not for you".
I don't think that there is much need for a lot of button, don't get me wrong. To me, just somewhat more feature full lever around the wheel - nothing fancy, just the same you get on most cars and a hud so that the rest of the family can indeed watch Netflix while the driver does not lose completely every driving information. Job done, a taste of the future, but not completely compromised experience for the poor sod that has to drive in the present.
[1] A lot of people that know more than me are skeptical this is even possible short term, but with no money at stake I'm happy to dream.
