it depends on if you consider cabinet doors a door. If you do, then I have 52 doors in my house alone. All houses on my block are similar, but ill round down to 50 doors per house. There is 55 houses on my block so 50 × 55 = 2750 doors. Ill add an additional 20 doors to account for detached garages, bringing my block's total to 2770 doors. My small town has 21 blocks total 2770 x 21 = 58,170 doors in my small town alone. I can guarantee there are more doors at least in my area then there are wheels. I can't even imagine once you start adding in all the doors in skys****ers and apartment buildings there should be no question that there are more doors than wheels.
