>In the US at least, the top killer of drivers are trees on the side of the road. A decade or so ago the Georgia Department of Transportation tried to do away with the trees between streets and sidewalks because of so many fatalities coming from collisions with trees. Clearing out an "automative recovery zone" as they called it likely would have saved lives of some people in vehicles but of course it would increase the danger to pedestrians, who might or might not be present at that moment. Lots of trade offs in these types of analysis and not all of them are always immediately obvious.
