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.

Toys heavily skew the balance though. Toy cars tend to have 4 wheels and no doors and dollhouses tend to have at most one door but toy cars heavily outnumber dollhouses

@gbargoud @michael @fesshole Lego is the largest manufacturer of tyres, so on that basis I'm going wheels
@sldrant They also manufacture doors! But yeah probably not nearly as many as wheels.
@Datenegassie they do, but I don't think they're the largest manufacturer of them. Wheels on the other hand is apparently true and a fun pub quiz question. Also thinking about the mou tain of lego we have in the house, wheels outnumber doors by a huge margin
