A car seat is a chair of sorts. If there’s a TV in your vehicle, the interiors could be a make-shift living room. The back seat could work as a bed. I’m surprised that more people don’t park their cars inside their homes and buy so much furniture instead.
I’ve seen these before: indoor cars. They are really shy and typically drive away and hide when guests come over. These sort of indoor cars would get eaten alive if they made it out onto the roads and highways.
