But that’s still a compromise in convenience. You’re trading not dealing with one problem for not dealing with another. You’re making a qualitative judgement about which problem you care about the most. It’s not reasonable to assume that everybody cares about the same conveniences that you do.
I prefer the convenience that doesn't eventually set the atmosphere on fire because of mass CO2 release. Car free areas, especially integrated with housing drastically reduces the amount of travel necessary.
Funny thing is for cities with cruise ship ports cars are minor priblem: https://www.thelocal.es/20190606/barcelona-and-palma-ranked-...
And for those blancket ban for four wheels won't even make a dent.
Interestingly general perception is to get more cruise ships!
