Chances are if you make more "quality of life" laws you'll either have some schmuck causing trouble when enforcement is nowhere to be found, or they'll be used as excuses for cops to pad their stats by arresting first and asking questions later, with most of the punishment hitting minorities, as tends to happen in the U.S.

The problem is cultural. Another poster here mentioned Japan, where busses are pleasant. After all, that is a place where "the nail that sticks up gets hammered down." If we really want public life on par with Japan or Europe, change has to start with each and every one of us. No government program or well-funded startup could ever do it alone.
