What is the word to describe someone who does not care about other people socially and publicly, that is a word or phrase which could describe behaviors such as littering, cutting in a line, talking on a phone in a theater, or arbitrarily and capriciously changing lanes when driving.
I googled and found some options: selfish, thoughtless, and antisocial.
However, in my opinion (which may not be accurate) selfish and thoughtless are not necessarily "socially and publicly". Antisocial seems to describe more a mental state rather than a behavior, not to mention that it may be too strong because it also implies arbitrary and capricious killing, robbing, stealing, and other crimes.
