I intend to be an early adopter of these subscriptions, but there's a key item they don't overcome: kids. When you have kids you don't just have to bring them everywhere, you have to bring lots of equipment everywhere. Baseball, hockey, football, etc. has lots of equipment that people are accustomed to leaving in the back of their vehicles. Same goes with strollers and diaper bag for babies. I don't know how we'll overcome that, most families will presumably still need to own at least one car. However, many two-car families should be able to downgrade (upgrade?) to one car and a subscription.
