When cars learn to 'transform,' do we really need a car?

When I was a kid watching Transformers, what fascinated me most wasn't Optimus Prime's justice or Megatron's ambition, but that split second when an Autobot transformed from a metal box into a towering giant. Back then, I thought: if a car could transform into a living room, bedroom, or even a study, how amazing would that be? Today, Xiaomi's Pengcheng N90 Max "Versatile Space" experience video seems to have brought this sci-fi concept into reality.
