I wish we had a neighborhood island. The road we live on is a quarter mile long (so, short) with few houses. It ends in a road where cars go 40+ mph. That road is awful - not only are there no sidewalks, but it twists and turns, and the road is cut into a hill with steep unwalkable slopes on either side. At any point a car could be coming downhill around the bend and your options as a pedestrian are to hope they see you or to just get run over.
