Still, noise is a major factor. Just take the mayor's comments from the article and the opening sentence:

> In Pontevedra, the usual soundtrack of a Spanish city has been replaced by the tweeting of birds and the chatter of humans

> “Listen,” says the mayor, opening the windows of his office. From the street below rises the sound of human voices.

Noise is the #1 problem with cars. Walkability and space issues via parking are #2.
