> It might also be related to the fact that both parents are more likely to be working today than in the past, thus less time available for driving the kids around.
I don't think so: Back in the days when Mum was more likely to be a housewife, families were also much more likely to possess only one car, rather than two. And that one car was parked outside Dad's job during the workday, so Mum couldn't drive the kids anywhere unless Dad was around to do it himself anyway.
I can see the argument for that, but having grown up in the rural areas of Sweden, almost everyone had two cars. Usually one half-decent and a second much less so. This also don't account for tractors.
A crappy car that cost around or less than $1000, standing there for the primary reason that two adults with children has an occasional use for a secondary car.
