I'm saving your life, bitch!

On my way back from work. It is getting dark, a mixture of black and red that makes things and people almost invisible.
I'm driving, hungry and eager to be home. I saw some movement in the middle of the intersection in front. The light is green and there are no car.
I flashed my lights to high beams to see better and I can now see a woman pushing her bike. She is crossing, dressed in dark color, probably en-route to the nearby club.
Another flash to warn her that she is totally invisible to traffic but that flash is misunderstood and she raises her hand to give me the finger. I gave it back to her resisting the urge to think that I should have zoomed by her and her bike.
