I've started asking people the thought experiment "are there more doors or wheels on planet earth?". I don't really care about their answer, but the speed at which they ask ChatGPT allows me to assess how much I care about their thoughts and opinions on other matters.
Cars have 4(ish) doors and 4(ish) wheels so they don't matter. Bikes have 2(ish) wheels and no doors. Houses have ~10 doors and no wheels. Nothing else has wheels or doors. There are likely not 5 times as many bikes as houses in the world. Ergo, doors.

@michael @fesshole
I currently sit on a chair with 5 wheels, and there are small furniture pieces in this room with a total of 18 wheels...
But also 8 cabinet doors.
I don't think it's that trivial.

...also, do mouse wheels count?

@Anke @michael @fesshole Plus the two wheels inside the mouse that determine X and Y movement. (LED mouses need not apply!)
@Anke @michael @fesshole Aeroplane wheels. Some of those big ones have hundreds! (Antonov, Galaxy) Plus those low loader trucks and trailers with around a million wheels!

@NormanDunbar
Trains! freight trains especially have way more wheels than doors, and they're long!
