That site is geo-blocked in my region so I have no idea what it says but I'd just like to point out that
A: the USA actually exports a huge number of used cars so the average life of a car sold in the US will actually be longer than the average age of a car in the US.
And B: without a significant number of cars way older than 20 years old, there's no way for the average age to be 12 years old and only 24% be over 20 years old. So a bunch of that 24% have got to be 50-60 years old. Either one of the stats are wrong or a significant portion of cars are lasting way longer than either of us were guessing.
Also you can appreciate the experience more just because of the aesthetics of a product. This is a well documented phenomenon. If it's not your thing fine, not everyone has to like the same things. I find for example fancy dinner sets to be ridiculous. Doesn't mean that I think people who own them are dumb for liking them. I have friends who break out their grandmother's china for Thanksgiving. I'd never do that but it makes them happy so good on them.
