Never waste a good crisis? Now that mobile bubbles are hot these days, and flying became scary, we'll definitely see more of these.
All logic evolutions. Electric platforms, smartphone as infotainment base, a 100% horizontal pop-up, probably full-solar roofs and triple floor rail pairs,...allowing a free plan with full-flexibility. So the theoretically perfect concept.
For the sake of reference to the old icon the roof is quite small, but then it's also logical to put the kids up instead of the adults. I must say I prefer the silhouette of this 'revision' to the poppy e-Bulli'.
Anyhow, just another designer's impression. Come and see again in 6 years.
