F'real they're just better SUVs. I tried googling it, but the internet's very helpful answers were "they're not cool" and "SUVs are more popular." I'm convinced it's manufactured desire. What really happened to the minivan?
Edit: Apparently wagons and minivans still exist, they're just sold as SUVs.
I literally don't think there is a single new model of traditional station wagon for sale in the United States (maybe a Mercedes or BMW?? one of the luxury ones has one I think)
Edit: yeah the Outback is the only non-luxury one and it's sold as an SUV https://www.foxnews.com/auto/station-wagons-usa
