I was at an intersection and I had a stop sign. I had inched up to see down the block because of obstructions. I didn't see anyone coming so I began to move again and when I got about halfway out into the intersection I saw the other car coming down extremely fast (think 35-45 on a 25) I stopped the moment I saw her and she continued to move, she didn't appear to brake until she hit me. She didn't have a stop sign.
