Plug-in hybrids are becoming more common.
Thus the consumer comes into posession of a vehicle that can be plugged into the mains.
Most such vehicles are equipped with a reasonable sound system and internet connectivity.
Why leave an asset unused for a portion of the day ?
You own a small
cabin with comfortable seats, heating and air conditioning, surround sound and other gadgetry.
The addition of a suitably positioned HD video projector(s) and opaque screens on the front and side windows can give an immersive, possibly 3D immersive, visual experience. It costs a lot less to heat or cool than a house. If you want to play F1 racing games, there's a steering wheel and pedals right there; a few design tweaks and Flight Simulator is equally possible.
You can be "right there" in the front row of a Heavy Metal concert with ease; in such a confined space, the audio power needed to rupture your eardrums and cause bleeding from the eyes and nostrils is comparatively modest.
And you can use these facilities when away from home, because they're right there in your car.
