I fucking love wheels vs doors. My entire workplace is about to start throwing chairs. Thank you OP.

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

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.

wheel's by several orders of magnitude

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.

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

I think SciShow did a thing like this for Eyes vs Legs.

It comes down to definition, but if one, but not the other, definition include biological parts then that one wins.

If no biological being has "wheels" but say, a valve, is considered a "door," then doors will always win.

But again, it comes down to definition.

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.

A better debate would be wheels vs hinges.

Because I wouldn't call a window a small door for example.

I say wheels: trucks, trains, planes, chairs, skateboards, roller skates, toy cars, small cabinets with wheels, bikes, motorcycles, scooters, wheelbarrows etc have more wheels than doors.

Define both. Does a doorway with no door but instead beads or a curtain count? Is a tiny door a door? A cosmetic one? Are spinning and potter's wheels wheels? Casters on furniture?
