> I've also renovated my house recently which involved disassembling and reassembling some IKEA furniture. They're still fine.
Indeed, I still have all of my original IKEA furniture after 7+ moves - none have "fallen apart". They just require partial disassembly to move. My IKEA desk and Billy bookcases are >20 years old and in great condition.
I'm not quite sure how people manage to be so destructive when moving.

While not a perfect representation of purchases, I believe the EPA chart (Fig. ES-3) I referred to shows the average of all for-sale models for a given year, so this should capture the increasing preference for larger vehicles. Indeed, the horsepower and curb weight are shown as significant increases, even while fuel efficiency is improving (≥2005). It looks to me like the average fuel efficiency passed the 1985 peak (presumably driven by the 1970s oil crises) around 2007.
Clearly two decades of decreasing efficiency was not ideal, but I posit it may be the 1985-2005 period which you are mostly remembering. Going by the chart there was a fast shift to smaller and 'weaker' cars for highly increased efficiency 1970-1975, after which there was a slow continuous increase of power and weight - first occasioning a slow but relatively small decline in efficiency (compared to the 1970-1975 increase), but then changing to increasing efficiency as that became a more important factor for consumers.
Relatedly, while I am certainly not the target audience for the kind of advertisements that may encourage people to purchase more oil-based products, I cannot recall seeing any automotive advertising that wasn't clearly produced by a specific vehicle manufacturer. It sounds like you are suggesting 2nd and 3rd tier advertising by fuel companies for reversing the 1970-1975 reduction in consumption, but I'm not familiar with that space - I would appreciate it if you could direct me to any resources you have about that.
Tangentially, while some vehicles presumably have worse mileage than a comparably-sized vehicle from the 1980s, fuel efficiency has significantly increased since 2005 (after a small decrease from 1985-2005) while supporting continuously increasing power and weight [0]:
In the two decades prior to 2004, technology innovation and market trends generally resulted in increased vehicle power and weight (due to increasing vehicle size and content) while average new vehicle fuel economy steadily decreased and CO2 emissions correspondingly increased. Since model year 2004, the combination of technology innovation and market trends have resulted in average new vehicle fuel economy increasing 32%, horsepower increasing 20%, and weight increasing 4%.

For backup I use hourly & daily kopia backups that are then rcloned to an external drive and Backblaze.
Expecting it to be well explained to the general public is like asking all patches posted to LKML to include a lay-language explanation of exactly what the patch changes, without using specialized CS terms.

Typical cosmological models assume homogeneity, which IMO is a poor assumption with the lumpy universe we live in. I'm a fan of more exactly applying known models before inventing new terms!
