Are there more wheels or more doors in the world?

This question has been circulating the internet for a few weeks now and truly everyone has different opinions.

As many wheels that are on cars, chairs, carts whatever... I still think doors are superior. In my room alone I have three doors which means my house has a total of eighteen. Like think about across the world??

The question has already hurt my brain a lot but I would love to hear your opinions and input.
