This also reminds me of "garage startups". In fact, probably only a fraction of people around the world own a garage. If your family has a garage, it means you are probably among the top ~1% richest people on Earth.
There are probably about an equal number of people living in a home with a garage in China too, though it’s wealthier suburban areas as opposed to lower and middle class people.
They’re common in Japan, too, outside of the densest few cities. And of course there are plenty of other countries where garages are common, like Canada and Australia.
