Innovation for Rear Seats?

Something on my mind: it seems that there are lots of cool new innovations to the cockpit of cars, and the front row seats. For example, I love how wide and expensive the front seats and interior of the Tesla model three and Y. Yet, the backseats are a bit boring. I suppose the panoramic roof and rear windshield is cool, yet, what are some new innovations we could integrate? To simply add more legroom, more screens and distraction devices seems a bit basic.

The trend for only two passengers in the backseat?

A new trend for the Lamborghini Urus, is that the whole car only has four seats. Two seats in the front, two seats in the back. The same goes with the new Lexus SUV, which is a massive car, yet only has two seats in the rear.
