Most cars sold in the US are not aerodynamic so it seems a couple of mpg isn't the focus anyway

The US is filled with bubble cars like everywhere else. There isn't really much difference between cars across the world. Well, China is unique with like 100 automakers all searching for customers, but for most of the world, it's Toyota, VW, Hyundai/Kia, Stellantis, GM, Renault/Nissan, Ford as the top global producers and they sell everywhere. Sure there are some special models in local markets, but those are mostly rebadged versions you can get elsewhere.

Fun Fact: Along with the "Bees are disappearing" scare, which was just measurement error, there has been an "insects are disappearing" scare, due to the fact people's windshields are not covered with bugs like they used to be. However that is because cars have gotten more aerodynamic so fewer insects are hitting the windshield.

    According to this research the opposite is true:

    "The survey of insects hitting car windscreens in rural Denmark used data collected every summer from 1997 to 2017 and found an 80% decline in abundance. It also found a parallel decline in the number of swallows and martins, birds that live on insects.

    The second survey, in the UK county of Kent in 2019, examined splats in a grid placed over car registration plates, known as a “splatometer”. This revealed 50% fewer impacts than in 2004. The research included vintage cars up to 70 years old to see if their less aerodynamic shape meant they killed more bugs, but it found that modern cars actually hit slightly more insects."

    Or fixed? The suspected cause at the time was pneumatic planter dust-off and addressing that was as simple as adding a baffle to direct the dust to the ground, so it was quickly adopted once identified.

I think oil filter located somewhere sinful usually in cars that are aerodynamically sound.
