It was a carbon tax on gas that was going to affect the lower classes disproportionately. I don't think we'd see an uprising for a carbon tax on intra-national flights, which are much more of a business travel mode
People choose to fly rather than take the train because flying is usually cheaper. This ban also impacts poor people more than rich people.
Poor people don't fly that often
Because their train travels are heavily subsidized. And more recently, it became easier to carpool easily for long distance trips in France with Blablacar (before the pandemy).
As long as no one figures out what's been taken from them.
The riots were because filling a car tank would get expensive. I’m not sure people would not notice, until a majority of the population is driving electric.
