As a far future concept, I can see something like this happening.
And I think it’s great that BMW focuses more and more on the human interaction/interface aspects of the car since these are so closely related to the driving experience.
In the future, I also see the value of electric cars that become taller and short in the city, and flatter and longer on the highway. They could adapt to all kinds of conditions and to the amount of people inside. So I see shape transformation also happening on a larger scale plus in a more abstract sense, the mode of transport with a car can transform not just towards autonomous driving but more towards that of public transportation as well with multiple cars linking up, displaying swarm behavior or chained like a train.
