Many car owners certainly care about gas mileage. It might not be the most important factor but there is some consideration for it. Similarly, renters could care if informed. But cars and apartments are very different products, and you can get somewhat reasonably cheap+accurate estimates of the efficiency of one but not the other. So the whole point is moot.

Cars will last for 10->15 years roughly before getting switch out. Apartments hang around for anywhere from 100 to 1000 years.

The cost of retrofitting energy efficiency is massive compared to the cost of building an apartment with energy efficiency in mind in the first place. That's why striking on new builds is so important.

For vehicles, bad gas milage sucks and it should be regulated to keep it down. However, we are talking about products with somewhat short lifecycles destine to be melted down and turned into a new car in the next 20 years.

The median car in service in the USA is 13 years old, so I think your mental model of car lifetime is pretty outdated. For cars made today you should figure 22-25 years.

This says 16->18 [1]

Where are you getting 22+?

Definitely an update to my mental model though.

See recent paper, noting the trend and that the rightmost point of the trend is already 8 years ago. https://www.nature.com/articles/s41560-024-01698-1/figures/4

Very interesting. I wonder why there's an apparent discrepancy between UK and US life expectancy. The UK has more stop and go traffic, I'd have thought that'd be harder on vehicles.
