As you may have noticed, the building has a margin (aka sidewalk) around it, there is no value for justify-content that will effectively make the elements touch each other. Making it impossible for the car to actually reach the building. Same principle applies to Grid or Flexbox. If it was a padding, then it would be different... but as it is a margin, they won't touch.
That sounds great, but why not just say you were late because of bad traffic... you know, like the rest of us?
