What kind of human beings do this in traffic?

As you can see, the robot is green for me to go. But I can’t, because 10 000 cars (more or less) have blocked the intersection from the other direction. What irritates me is that I stopped at the light change before this, when I could see that I couldn’t get across without blocking the way for these people. These very same drivers then proceeded not to give a hoot about exactly that to me.
