One way to hold this phrase: a car swings off the track, four people fall on it, fuel goes in, tyres come off and go on, and in a few seconds it is gone again. Nothing about that stop is . It exists only so the journey can continue, and it is over almost before it starts. Every other use keeps those two promises: you take on what you need, and you do not stay.
可以想成這個畫面：賽車滑出賽道，幾個人撲上去，油灌進去，輪胎拆下來再裝上去，幾秒鐘之後車子已經不見了。這一停完全不是休息。它存在的唯一理由，是讓整段路能夠繼續。而且它短到幾乎一開始就結束了。它其他的用法都守著同樣兩個承諾：需要的東西拿到手，然後不留下來。
From the word’s history
Wiktionary gives the phrase as pit plus stop, first appearing around 1915 — literally the stop made in the pits beside the track, which is still the picture underneath every later use.
Wiktionary 記錄這個詞是 pit 加 stop，大約 1915 年前後出現，字面就是「在維修區的那一停」。這個字面畫面到今天都還撐著它後來的每一種用法。
