Doors is the correct answer.
People who think wheels fall under the trap of thinking everything that is circular/round is a wheel. The definition of a wheel is: a circular object that revolves on an axle and is fixed below a vehicle or other object to enable it to move easily over the ground.
Most people forget about the axle part.
The Hot Wheels thing is just dumb, if we are talking WORLD, Hot Wheels are really not all that common, like cmon now.
Do not discount the thunder of die cast metal!
"According to several sites, 16.5 toys are produced every second and over six billion Hot Wheels have been sold since 1968. That’s more than the number of cars that have been manufactured and sold by the Big 3 automakers: General Motors, Ford Motor Company, and Chrysler Stellantis.
To put it into perspective, a line of all Hot Wheels cars would circle the Earth more than 4 times, if placed end-to-end.
More importantly, two billion toy wheels are reportedly produced per year, so unless doors can beat that figure, that answer to the debate could truly be wheels."
