I think this is true for a subsection of this age bracket.
DS and DIL just bought a house. It's in an "inner" suburb, more citified than where I live, but still, they can't walk out the door to shops. But, there is a bus stop on the corner so DS can get into Boston for work. It's a 15 minute drive for DIL to get to work in another city-suburb. They have one car. So far, it's worked because DS either takes public trans or rides to work. If he needs the car, he has to stay up late to pick her up; she's a restaurant manager with odd hours. Eventually, probably when a kid appears, or someone gets a new job, they will need 2 cars. But, it will be interesting to see what happens when they move into the house. They have been living a very urban lifestyle and this is going to be a change.
