One reason for me comes from the method of tracing: zoom in, mark points along the longest straight stretch you can see, then pan the map, repeat, etc. If you're very zoomed in, you can't tell that the road will be straight off the screen. And sometimes you just forget not to. Or you're not certain that the road really is straight, etc. Steve
