tl;dr - there is a kind of bread that is traditionally baked in geothermally active areas by leaving it in a hot hole. This guy tried to make the same bread by leaving it in his hot car, but it didn't work so he finished it in a normal oven. A fun experiment to be sure, but not particularly interesting results. Whether or not it's worth reading the entire thread probably depends on how interested you are in repeated updates about how much some dough has risen.
