Here's my take on this:
I don't know about Europe, but the American infrastructure is crumbling. Roads, bridges, water pipes, power grids, etc. Sedans, wagons, and other smaller cars now are struggling to meet the needs of everyday Americans that drive to work and other life events. Wagons are no different than sedans and do not offer the same driving comfort as a crossover. Let's face it also, wagons have evolved. Crossovers are nothing but lifted wagons with bigger tires and ground clearance and most of them come with AWD standard. Like they mention in the video, the Subaru Outback is more of a wagon, but in reality it is a crossover. I love my wife's crossover, and mind you, I used to be a staunch anti-crossover guy myself. But now, I could never see myself going back to a sedan/wagon/hatch for DD. But whole point being, crossovers have a lot to offer in every single way as a transportation device. Very decent MPGs, more room, bigger tires, more comfort, AWD... crossovers are excellent choices.
