I’m willing to bet you do the exact same thing. The vast majority of people drive alone every day, and only occasionally have passengers. Do you have a passenger seat? A back seat? A trunk? If so, you’re buying for the edge cases, not the average, and you’re not special.
I would not consider my having a trunk as being an edge case as I use it weekly. Back seat less so, but still quite often. But if I didn't, I probably wouldn't choose a car that had them (assuming such options were available)
