In every state that i have driven in, And that is all in the contiguous 48, the law says cars are suppose to stop for pedestrians in cross walks. The Laws in California are so strict if you go through a pedestrian or Bike crossing you receive a very hefty fine. Medusa, although he had no right to hit your car he did have the right of way even if it was at Walmart. Stopping
is not optional, it is the law everywhere.
