Pushing a meme a bit too far there anon. If you've not heard everyone is wearing the yellow vests because the French brought in a ridiculous law that every car in France has to have a kit with a yellow high viz jacket, spare bulbs, headlamp converters, a warning triangle, a country or origin sticker (if foreign) and your own breathalyzers. You need this stuff even if you go on a driving holiday through France or pop across the border to do your shopping. It's obviously a money making racket for one of Macron's friends who sells this shit and for the government who fine people if you leave your high viz jacket at home.
