Nope. Not falling for it. NOT FALLING FOR IT.

This leads very quickly down a rabbit hole on what precisely counts as a "door" or a "wheel."

If you count toys then it's definitely wheels. Even if you didn't it's still probably wheels. Chairs, strollers, shopping carts, luggage.

Is a transistor a door? Then doors (and it's not even close). Otherwise wheels because gears are wheels.

Easily wheels. Every roller bearing in things like drawer slides, sliding closet doors, sliding shower doors, sliding screen or glass doors, etc. are technically a kind of wheel. A single door could have multiple wheels. Garage door segments with multiple wheels as rollers pre segment. Cars, bicycles, scooters, skateboards, motorbikes all have multiple wheels. Wheels aren’t just for locomotion. 18 wheel trucks have only two doors but obviously 18 wheels, not including any hand-trolleys it might have in the back for loading/unloading. Trains have multiple bogies usually with 4 wheels each and two to a car, 8 wheels per car and maybe two to four doors.

But wait, what about an office building full of hundreds of doors? Think of every office chair with multiple wheels. Desk drawers. Office carts. Elevator pulleys, doors, and guides.

Wheels win.

Way more wheels than doors.

Does this include rollers on conveyor belts or are rollers not included. If they are, absolutely wheels

There are EXACTLY an equal amount of doors and wheels in the world and they are being produced at the same rate.

Source: I just checked

Edit: Just checked, they are also destroyed at the same rate.

Ok I think this actually has way too much speculation and is asking the wrong question. Instead of "in your opinion globally are there more x or y", why not quantify it? Specifically in your instance, does your living quarters and personal belongings and other places you frequent have more doors or wheels? Go count them. We can actually solve this with enough data.

For me it's doors by a long shot. Almost nothing in my life has wheels. I live frugally and cheap furniture usually doesn't have wheels. I don't own Lego as other comments suggest. Drawers are not doors. Gears are not wheels. Eyes (wtf) and widows are not doors. The breakdown in my life is:

24 doors 15 wheels

Every time I've seen this come up, it turns into a kind of coastline problem. The closer you look at everything we've built you just start finding more and more doors and just as you think it must be the winner you start seeing all the wheels that go along with them (or vice versa).

It's impossible to know which one wins without very clear (and limiting) definitions of "door" and "wheel". Those definitions would have to be equally restrictive to both "doors" and "wheels" or else the limitations decide, not the world we've built around us. I posit that anyone claiming to have an answer have made up their own limits of what "counts" and those limitations are likely not equally balanced.

Im going to chime in here and say we expand the definition of wheels to include doors and the definition of doors to include wheels.

Problem solved.

Wheels, just because of Lego

Today, almost 50% of all Lego sets contain wheels.

And this is without getting into non-vehicle wheels like flywheels, gearwheels, etc

Team wheel here. I'd expect the sheer number of wheels inside mechanisms and machines to clinch it.

This has broken my brain.

I have 40+ wheels I can think of in my house. Chairs, carts, bikes, shit there's even one on my mouse. That's not even counting all the wheels in my massive Lego collection.

But then again... Cabinet doors, microwave, refrigerator, oven.... Fuck!

What have you done to me?

It's wheels, it's always gonna be wheels, most things will have 3 to 4 wheels, trucks have 2 doors 4 to 8 wheels, then you have the trailer that usually has 8 wheels and 2 doors, then you have any industrial machinery that pulls something throughit, because rollers are wheels, also, now I know people will say that houses have lots of doors, but think about it, your vacume has wheels/no door, your fridge has 4 wheels 2 doors, no matter how you try to play this game, wheels always come out on top, they're infinitely more important to modern society than doors are.

There are doors WITH WHEELS.

Thanks. We've only been at it for 20 minutes and this is ending friendships in my group chat.

I'm going to argue a little for team doors though I wouldn't say I'm confident.

Feels like are more things with doors and not wheels than things with wheels and not doors. So many buildings and cabinets and dressers and whatnot. Actually, think of an apartment building. A 1 bedroom apartment will have at least 3 or 4 normal doors plus cabinets and the fridge, times the possibly hundreds of apartments in 1 building, plus probably a couple dozen for maintenance, common areas, and elevators.

I do think how you define the 2 greatly changes the calculation, but I think doors do compete at least

An reasonably answerable but still interesting question is, does an aircraft carrier have more doors or wheels.

People are getting way to technical about it

Human made doors vs human made wheels

Balls don't count as wheels

I would say you need an actual door so the doorway between your living room and hallway doesn't count. That's a doorway, not a door

The issue is, what counts as a wheel?

My car engine has some round shit that spins for belts on it, are those wheels? I would say, for fun, no. It has to be a wheel... used for moving the object around, gears and shit don't count

I still think wheels win because there are lots of toy cars in the world

Well, cars have doors so I'm going with doors (most vehicles have doors)

I'm not going to weigh in definitively, but I would like to posit this question to XKCD or something.

Do gears count as wheels?

Easily doors. It's not even close.

I thought the wheels had it easily, but then I started counting cabinet doors and I'm not so sure anymore.

Fake doors? Real doors? Real fake doors?
