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."

    I say wheels.
    Because of Lego.

    Any pulley or sprocket is arguably a wheel.

    Just because they are round doesn't make them a wheel. Now if we count the individual balls in a ball bearing as wheels then wheels win hands down

    Searching the definition of a door at 2 am, befire i start checking average production data for home appliances like toaster ovens, air fryers, microwave ovens, etc. Fridges have doors. Doors have doors. Dog doors. A door can have two doors. A dog door and a spyhole door.

    Yeah no. Too broad

    It gets so much worse than that. Is an electrical switch a door? It's a straight bit that bridges a gap and rotates on a hinge. How about gears? Do gears count as wheels? They're round, they spin, and they apply mechanical forces on their perimeter.

    You can actually attempt to answer a question like, "are there more dogs or cats?" because dog and cat are relatively specific. You might quibble whatever wolves or lions count, but adding wild animals to the numbers won't change the math much. But door or wheel? Those are objects much harder to pin down.

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

    Any large multi-room building, like an apartment complex or a hospital or something, would drastically increase the door count. And if we're talking toys, what about toy houses? Do lego doors count?

    Hospital doors have to be out numberer by the stools doctors scoot around on, I think.

    1 office chair has 5 wheels. Almost every home has at least 1 office chair. And if we look at hospitals then it gets even worse because there are a lot of the beds have wheels.

    And then we can go even further. A lot of curtains use rollers which are wheels. So if I just look at my apartment, I probably have 15-20 doors(cabinet doors, etc. but a lot of the normal doors are sliding doors which use wheels) and probably 50-100 wheels. And that is probably undercounting the wheels that are there by a lot.

    Yeah, but does that hold up globally? There are 8 billion people out there, plenty without computers or curtains. My guess is wheels only win cause you can also count defunct wheels on landfill bound chairs and things-- is a door still a door if it's unhinged and scraped?

    Cabinets man. Look around in a kitchen or bathroom, every single house in the world has a ton of doors.

    Hotels, they're basically made out of doors (including furniture and appliances). Cruise ships take it to a whole other level.

    Commercial lockers. It's ridiculous how many doors these spaces have.

    Wheels probably wins because of the ridiculous amount of toys, but it's a fight.

    I don't know if this is true, but when I was doing training in the tyre industry, one of the leaders liked to ask, which company, globally, manufactures the most tyres? obvious answers included Michelin and the like. Their answer? Lego. apparently they pump out more rubberized tyres than any other car tyre manufacturer

    again, not sure if actually true, but it makes me think there a lot of wheels out there. however, Lego also makes things with doors...

    I wonder what the rubber volume is like in comparison rather than numerical volume.

    The materials are different, but a Lego tire is like 2.5 grams. A car tire is, let's say, 10kg - some are lighter, others heavier.

    Michelin alone produces like 200 million tires a year, Vs Lego's 300 million, so car tires use more materials by several orders of magnitude, it's not even close.

    Think about how many wheels and doors you have in your place. Every cabinet and oven has a door. Every building is chock full of doors. I feel like most people only have a few wheels around compared to doors.

    Gears. The car's transmission alone has probably 30 meshed together on its own, not to mention gears are in everything. Bearings too. Is a sphere a wheel? Casters, slide rails with wheel runners, washers, and conveyor belts feel like they deserve a spot as they are round locomotive devices.

    Doors also are very rare in nature, but a rock pretty regularly forms the right shape for a wheel.

    I might be missing the forest for something that looks like trees, but it feels like there are overwhelmingly more wheels than doors.

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

    There's like 16 billion doors just in people's eyes. Then doors no longer in use underground for 10k years. And windows are just bad doors.

    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.

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

    I'd classify them more as gates, not doors.

    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.

    If ball, needle, roller bearings count as wheels doors lose by a loooooot

    Every door that is opened by a hinge has AT LEAST one wheel associated with it 🤷

    Wheels win 😈

    I don't think that is accurate, the majority of door hinges I am aware of have what I would call an axle, but no wheel.

    There are definitely some doors on wheels though, plus everything with wheels has at least 2 so I think wheels win

    I feel like most things with doors have more than one door too, but I guess that depends how granular you get... For example, my kitchen has like 30 doors. But like, that one singular cabinet only has one door...

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

    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

    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.
