Grrrr! I hate that as well. Pretty much every person who's been driving in urban areas for many years has had some close brushes with dark-clad pedestrians. It's clear that most of them don't give a thought to safety or visibility, especially the ones that seem to love jaywalking at night while wearing dark sweats and black hoodies.
