Honestly, kind of amazing to see a big city actually pull it off. So many places talk about reducing car dependence and improving air quality, but Paris really committed - and the data speaks for itself. Of course, the pushback from drivers was inevitable (it always is), but it's hard to argue with 55% less PM2.5 and cleaner skies over the Eiffel Tower. That's not just good urban policy - that's public health in action.
