There was actually just a very detailed gastropod episode on this, but the tl;dl version is that a vitamin isn’t a specific thing the way a protein or a carbohydrate is. It’s anything that the body needs in small amounts that isn’t something else

My cat did this in many cars until I got an EV. No idea what’s different, but I’ve tested it in a relative’s series hybrid and he gets a bit annoyed for a few minutes and then settles in electric, but still complains for hours in gas or parallel hybrids

Would love something like this for field notes, though for my uses a eink screen would be preferable. Hopefully this or the equivalent takes off and we can start getting fun variables in the future!
