Operating a powered vehicle on public streets for your own convenience, pleasure or profit is a privilege. That privilege comes with responsibility. That responsibility is simple: do no harm. If you can't drive safely for any reason, don't drive. Driving safely means, at a minimum, not hitting pedestrians with the right of way. Period. It does not matter what the pedestrian has chosen to wear. If you think you can make a legal right turn on red but you can't tell for sure if you see a pedestrian waiting to cross, don't make the turn until you have made sure. If you get an impression that you see motion at night, you probably do: in darkness, the human eye does a better job detecting motion than shape. That fleeting impression of something moving could mean a human being, and until you've identified it, stay stopped. You and your car can mange to wait to make the turn, but the pedestrian can't make do without their life. Adjust your speed to the visibility. If you can't see a pedestrian in a black coat in a crosswalk in time to stop, slow down until you can. You will get where you want to go a whole lot earlier if you don't have to stop to explain how you injured or killed someone along the way.
Motorists keep putting more and more onerous conditions on vulnerable road users. It has to stop now. The appetites of car users for speed and convenience already dominate most of the usable public right of way. Motorists have an unconditional responsibility not to injure pedestrians using the limited public space left them. Don't hit pedestrians in crosswalks, at four way stops, in crossovers, or on the sidewalk. Just don't do it: full stop, no excuses.
