Red Means Stop, Green Means Go U Idiot

I thought it was somewhat irritating that in Germany, you didn't cross the street until the light turned green - no matter if there was any traffic or not. In addition, you didn't even think about crossing if you wouldn't make it across in time. Now I'm appreciating this cultural difference as here in Chicago, it seems nobody cares what color the light is - red, yellow or green. People will cross when and where they want. As a result, I was only inches away from running over someone today as she slowly made her way across the street when the light was green for drivers to go. I tried to teach her a lesson by honking, but she probably assumed I was just bitter. Next time, maybe I should give her a nudge - with my bumper.
