interesting, but i'm not sure this is the whole story. google maps's stroke width for roads seems to be based on some measure of traffic or connectedness. from my experience, roads that see fewer cars and fewer intersections tend to show up less prominently. since google has vector data for maps, my guess is they algorithmically weigh and display routes and this leads to dead ends being fainter than other roads
