The point being here, there is "it would be nice", "some fit the model where this would work", and "there are a lot of cases where this won't work". Or even more fundamental things when talking about little ones like things like car seats. Maybe it is "choice", but there are a lot of people out there where the "choice" around their vehicle is closer to that of it is lived in, may have books and papers, clothing, toys, etc. (maybe food as well) that will not conform to this scenario. Walk through a grocery store parking lot sometime and observe the state of vehicles as people get in/out, etc. my bet is on a sufficiently large pool would be in the condition where utopian sharing doesn't make sense. That said, if there was a mind shift because of an overall benefit, it could happen. But, that is a long way off.
