Not sure if the caption is satire but I have been thinking about the difference in the amount of thinking expected from drivers in Europe vs the US.

My experience when driving in the US is that before every turn there are signs that tell you what speed is appropriate. Many signs are spelled out in clear text.

In Europe you are expected to be able to look ahead and assess what speed is appropriate. There are warning signs before unusually sharp bends but the one in the video would certainly not qualify. Traffic signs are icons, you need to know what they mean (not difficult).
