Its amazing to me how cheap these changes are, and how much people love them after they are implemented. You go to a neighborhood meeting in the US and all you hear about is "loss of parking", "traffic", but when you remove the cars, everyone loves it.
The yellow jackets in France started as a protest against increase in tax on petrol. The previous president in France, Hollande, had to roll back a toll system. It took Paris 2 years of legal battles to close the roads along the Seine.
The major difference, compared witg the US, is that at least in an urban setting, in Europe you can imagine other alternatives.
The problem of the US is that outside of major cities, the entire country was designed and built on the premise of cheap, individual transportation. Everyone has his own little house with a little garden. No town centres. This lack of density means that public transport or bikes will never be able to be able to provide a serious alternative to the automobile, and so people will never given them up.
