Dude have you ever been to Paris? Have you seen how the people live? What is that tower of ignorance that you're speaking from? Anyone who drives an SUV in Paris likely doesn't have a real, traditional job at all. The costs associated with owning a large vehicle there are absolutely insane, starting from gas, taxes, and parking costs, ending with literally not being able to go into some streets if your vehicle is too large. It won't be a problem for these moneybags, don't speak for them.
The whole point of the regulation is to decrease the use SUVs in the city for health and safety reasons. If cost doesn't matter to them, then this regulation is meaningless. It seems the people who pushed for this, and presumably most of the people who voted for it, disagree with you.
but I don’t really like the idea that something you already own outright can be regulated to the point where it’s highly inconvenient or impossible to use.
It was highly inconvenient for all of those people who had cars that took leaded gasoline to have to either keep buying lead substitute to put in their tank at an extra cost or sell their car.
