Wow. That seems such a sad and limiting way to live your life. I love how I can use my cars to go anywhere at any time without depending on anyone else. And my family and I do a lot of optional activities. Different perspective, I guess.
Mostly true in my experience. I used to get away a lot more when I had a car and could just decide to hit the road whenever I wanted than I do now that I either have to rent or plan earlier and buy train tickets. It's purely friction linked by the way. I could still do all the things I did and it would actually cost me less money in the end. I just don't.
We tend to take more rides in the decoupled model, I'd think.
It might make more sense to say "in a car ownership window" than "in a month" to prevent heavy months (say, holidays/vacations) from seeming problematic and lighter months (not doing much besides working) from implying that you're winning more than you really are. Assuming sufficient buffer of funds, that is.
