Here’s the situation, and I…
Here’s the situation, and I want to emphasize that I’m the person this happened to: Everything was normal, and I was driving with FSD engaged. Suddenly, the heater stopped working (no warm air, just weak cool air), which caused a temperature change inside the car and led to the windows fogging up. I couldn’t stop immediately to address it because it all happened so quickly, and I was in the middle of a turn. Within a few seconds, FSD completed the turn, and I took over the car within the next 30 seconds. I then pulled over to the side of the road and manually defogged the windows. Only after I could clearly see with my own eyes did I restart the car and get back on the road.
I’m not an idiot—I would never entrust my car or life to FSD when I’ve completely lost visibility. However, as the person directly involved in this situation, I can say that in that brief moment, FSD handled the situation exceptionally well. Throughout the drive, even with snow-covered roads and occasional icy patches, it continued to perform impressively.
