Depending on where you are. Some places have a lot of street activity. some none. In baioth cases you will find that it peaks when people are going to or coming from work.
A friend of mine and her husband do. They don t even own cars. There s either public transportation for work, or everything they need within walking distance.
I live in BK, and it depends on the streets of course as mentioned before. BK has its good and bad parts.
the majority of New Yorkers do not have acces to a car, walking is a necessity all over.
