I'm guilty of this sometimes. 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.
