BMW and Toyota have famously used bio-derived insulation reported to be like catnip for rodents.

The bio-oil plasticizers also migrate out more quickly in thermal cycling than the old dead dinosaurs approach. Hilariously, when I asked my mechanic about getting an M5, he laughed and explained that the radiator components are known to turn brittle and crack after 5-6 years because of this.

(I don't envy automotive folks. The stuff they have to deal with is next level.)

Last time I had to call AAA to jump my car, the guy opened the hood very carefully and told me he’d had three rats jump out of engines at him that day, presumably because of the “soy wires.”
