Zebra crossings are a joke.... I slow down when I see them and I stop when I see people waiting at them to cross. They seem shocked to see that I have stopped. I'm sacred that some day I'll get rear-ended being stopped at one.
I have had many cases where I stop and the people start to cross when traffic in the opposite direction of me doesn't stop or even acknowledge folks are in the crosswalk. I flash my lights, honk my horn, and at times, roll down my window yelling out 'zebra crossing'.
Never think you are safe as a pedestrian walking in a zebra crossing. I have had to avoid vehicles many times while walking in a zebra crossing. These days I enter the zebra crossing while waving my arms and yelling out 'zebra'.....
