There's more than one similar city which had plans to drastically changed what cars are allowed to do, and when, and the story is similar: people go insane, usually shouting out claims like 'city is going to die' and 'commerce will suffer greatly' and so on (which if I'm not mistaken they do not have any proof for, also not from previous cities where the same happend), and the effect then gets axaggerated on social media.
From what I've seen what follows next is usually the same: the plans are executed, as long as you don't insist on driving your car to the store front in the middle of a medieval city, you're happy because the city became more pleasant and after all there's a ton of parkings, studies one year after execution show less severe accidents involving cyclists and pedestrians, no measurable effect on commerce and less pollution. (again: this is only what I recall from having heard and read here and there, I did not research this in depth so reality might be different)
