I drove a cab in anchorage at night.  In 2009 I watched a driver drive up on a sidewalk and run a woman down, I sat with her untill the ambulance came. Do you know he was in the middle of the road. How do you know the driver was sober. Think about it its 3am the highway would not have a lot of traffic on it so why didn't the driver see him. Was his lights off. A sober person would have seen him and stoped not contuinued on.
