Anything we do that benefits the community will be recognized by businesses and consumers alike which will lead to leaders in our community and the media to recognize it, as well. This way, maybe we're not the first ones to have fingers pointed at us when something auto related goes bad and maybe, when we'd like to do something that involves public and private property and/or involves the public, we're more likely to get a city that approves and a community that is willing and open.
What goes around comes around, anyway.
Besides, if nothing else, you do good things to do them, not because you expect something in return.
