I think eventually minivans will be a quite popular format for autonomous vehicles. Full size buses are inconvenient for suburban streets, while vehicles for single occupants may be priced out in on-demand situations for many trips.
Already, minivans are very popular in unofficial public transport systems in many less-developed countries. In Morocco, grand taxis are old Mercedes sedans that leave when full - they're cramped and reckless, and I bet minivans would be preferred if they were more readily available.
I think we'll see many people commuting in the near future by shared transport decided by efficiency algorithms and based on demand and prediction. Minivans could get 5-10 people into the CBD quite effectively in peak hour rather than the 1-2 people/car we see now, and without waiting for a bus or walking 3-5 blocks to the stop.
A minivan with swappable internal components could easy convert to sleep four people (a family on a roadtrip), or have bench seats facing a card table (like a train), or have four reclining seats (like a plane, watching movies on VR headseats).
I like your point about in-car leisure. As autonomous driving unlocks it in a new way, I would expect our for forays into autonomous vehicles to attempt to highlight the luxury of this. It certainly seems more appealing than tightly gripping the arm rests while you observe how the robot is doing.
I would add that interchangeable parts are probably not going to be a focus. The auto industries are pretty efficient at managing large supply chains to service several different models. If convergence was economically important it would happen more often.
More so a convertible interior than interchangeable parts. As with how RVs convert dining areas to beds, or how an SUV's rear seats fold down to provide more cargo space.
I think a comfortable, self-driving car would be a quite pleasant alternative to flying in many cases, especially if you're likely to be hiring a car at the other end anyway and have a good amount of gear to stow on a trip.
I think a lot of it too is room for batteries. When you make an EV sedan you've got to either use a T battery, or use the entire width and breadth of the bottom 4 inches of the floor.
But, a minivan or SUV/CUV? Those things ride high as a preference. I bet you could put a full foot high of batteries under that design and no one would even notice a change. Look at the Outlander PHEV, for example. It's got 12 kWh of low-density batteries in the floor and they didn't have to compromise interior space at all. I've always wondered why those things weren't the first vehicles to get electrified.
