Why choose an overturned car? Not just because it's overturned but because it indeed makes for a comfortable campsite.
Those with experience understand that the roof of a car is actually very soft — practically a natural soft bed. It's also spacious, unrestricted by seats, and one person can lie down with room to spare.
"Moreover, a small space actually has its benefits, as it can provide a sense of certainty. Open, dark, unknown environments make people feel uncertain, and that feeling of uncertainty is hard to bear."
Closed, controllable environments offer much higher certainty. There's nothing unknown, everything is within one's capabilities, and it feels safe and comfortable. It's the same reason why cats like to squeeze into tight places."
With a stable environment, people can rest better and use less energy."
