This was essentially my attitude when I bought the RSX 3 years ago, but experience with the RSX has shown me that it's an added hassle not being able to put people in the back seat. Maybe it's just "poor, starving 20-something in California" syndrome, but more often than not, my friends and I carpool in order to save on gas and to use carpool lanes (which are 3+ occupants). I do use my car to drive people around, and so do my friends. It's inconvenient and it's rude to always be mooching off other people for rides. While the taxi analogy may be true, the backseat is also a very valuable resource for utility and convenience.

I love my RSX. But having riden (slept) in the back of my own car on a road trip, it is not comfortable, and I wouldn't subject anyone I know to that either. But again, that's just me. 3 years of driving the RSX have made me understand that I need a 5-door, even if some other people don't. Like you said, we're the ones that live with it on a daily basis. As my daily driver, the RSX wasn't meeting my needs on a lot of levels because of the backseat.
