Well, but on the other hand If I try to convince someone to start mapping in 
his area and he even doesn't see anything in his area(because it's 'only' 
segments) I normally get an answer like: 
	"Why should I start in the middle of nowhere ..."
	"There are not really many people out there doing things 
	 for this lonesome project, ..."
So I think that at least seeing that there is already something done makes 
people think 
	".... Oh it's only correcting these 2 or three streets ..."
And everyone who already started mapping knows that once you really started, 
it's pretty addictive, which makes it hard to stop  ....

I don't care about the color, but I thought a 1 pixel wide dashed light grey 
line would be good.
