That guy got extremely lucky. In almost every case of a wildfire, even professional firefighting teams with the most powerful equipment can't save homes in the path of the fire.
I grew up in Southern California. Almost every summer there were wildfires in the hills. I could just see the orange glow of the flames through the thick smog. Back then there were some big fires that damaged homes, like the Belair fire, but it was rare. Now it's very common.
