Can I just say, as an American who moved to Europe in 2022, the lines at gas stations are crazy to see! In the US, I had never had to wait for more than 1 or perhaps 2 cars to fill up, even right off the highway. Here, waiting seems to be common from what I've seen if you're traveling on a busy weekend. My experience driving has mostly been confined to the Benelux region, so perhaps it is different elsewhere on the continent.

I do like driving over the border to save 20% on fuel prices though!
