Limited practical options in the US definitely helped push the move to CUVs.
edit: whoops, was looking at the "Cross Country" variant of the V60/90, which is a raised wagon. The normal V60/90 wagon I'll concede to be sufficient for most people's needs, but it's only been available in the US market since 2014.
I'd like to believe all these automakers aren't going through the trouble of safety testing and certifying wagons without demand being there. The hatchback version of the Golf/Mazda3/Impreza seem to be selling well enough.
We have three kids in car seats. Getting a baby carrier out from the middle of the BMW is a mess. It's simple in the Mariner.
I frequently need building materials for things around the property. Where do I load a car with shovels, 2x4s, plywood, and hardware cloth?
I don’t know what hardware cloth is, though.
I'm pretty sure getting car seats in and out of cars have improved in the last 24 years. A baby carrier is probably more convenient in the front passenger seat, don't forget to turn off the airbag.
Most people around here just put a trailer behind the car if the stuff doesn't fit in the back with the back seats folded.
I'd also like to point out that of course some people need 4x4 with higher ground clearance. But do the majority need it?
True 4WD with high clearance is needed for some unpaved mountain roads, but only a vanishingly small number of people need that.
