I have a small car (regular hatchback) and a lot of the parking spots in the very large airport in my city are just marginally wider than my car. If you can’t get the spot at the end of the row, the only way to park in some of the buildings is to offload all your passengers, hope you find a spot where you can park “right door to right door” next to someone else so you can leave just enough room on the left side to squeeze out.

The parking buildings were built when cars were smaller than small cars today, and as the passenger count increased, so did the need for more spots, in a 0 sum game. They just split the cake in smaller slices.
