Le Taxi
Because of the Macron link I think I should issue a cautionary warning. Le Taxi is French police slang for a police truck where they put people they don't like and beat them up.
I had the temerity to complain at a Ryanair desk about Ryanair causing me to miss a Ryanair flight, and the dastards went and called the cops on me. A rotund, uniformed pensioner pulled a gun on me for reasons beyond my ken, and said he was going to call me a taxi. It didn't sound like much of a threat but I only got a B in my French O Grade. Some Arab French guy rescued me and explained it. Say what you will about Arabic French but they know fine well the police vernacular.
Second tip: never, ever enter a queue in France that has a British/American flag on it - it's a trap!
TL;DR - If a French cop mentions the word taxi then call your own taxi and flee.
