I would not describe travelling alone as "very specific circumstances." It is extremely common. 70% of all car trips are solo, and the average number of occupants for all car trips is 1.5. That you can get more bang for your buck driving if you have enough passengers and luggage doesn't change the fact plenty of people don't.
You are entirely right, because 98%+ trips in a car are commutes or errands that average 6 miles in distance.
But, that is not the topic of conversation above -- we were talking about trips 600+ miles in distance. These are almost exclusively not commutes.
Averages don't necessarily describe your whole data set. Just like how the average person has around 1 testicle, this data is also multimodal :) ... People commute alone, but they go on vacation with friends/family.
