I remember the smoke hovering over San Francisco, CA during the fires in late 2018. It was the worst I've personally experienced. I had an office job at the time. At the end of the day I didn't want to walk home in such poor air quality, so I ordered an Uber. The driver had been driving in that smoke all day and it caught up with him. Halfway to my home, he opened the door, puked his guts out, canceled ride, ended his shift, and I ended up walking the rest of the way.
That's wild. It makes me wonder how many people know what the circulate internal air button does and if it would be sufficient or not to prevent the above happening for the driver
