The last 5-10 years have been primarily reacting to buyers (and choosing not to market sedans more) but there was a specific concerted push to change market opinions toward SUVs and SUV-like vehicles, so I'm inclined to instead blame marketing with a healthy sprinkling of availability.

The last time I bought a sedan I really had to go out of my way to find the only one on the lot that happened to be in my budget and in my desired age/mileage/mechanical shape, and I happened to test drive all 5 sedans that they had on that lot. If I were indifferent towards the body/chasis style I probably never would've looked at the sedans just by pure math of there being easily a hundred or more SUVs, a smattering of trucks and vans and that was about it

I mean, for me they effectively replace the car. We own one, but since we have the e-bike, I don't drive at all. I use the trailer for shopping if needed. And yes, we used the trailer + the small seat behind my seat. Basically all three kids could ride with me, but the battery depletes fast and I am not sure about the general strain put on the bike's structure with so much weight. The bike is not technically ours but leased from the company my wife works at. In Belgium, at some point the taxes get so high that people choose untaxed benefits at work (like a bike leasing or vouchers, even a company car) instead of salary hikes. We now own a second e-bike with two separate seats so we can have family trips. We'll see how it works. To clarify: I do NOT believe that you can always replace a car with an e-bike. But in the rather wealthy area where we live, the bike infrastructure is great and everything is very walkable, so it is possible to greatly reduce your reliance on cars. The Netherlands are far superior to Belgium in this respect.

You're certainly entitled to your opinions and interpretations.
