if i pick 5he exact location i am standing on the map, with the marker, it will tell the drivers i am up to a block away. also, i have had drivers drive right past me while i uave been wearing work and street clothes and had a backpack on, and then cancell the ride after passing me. there is no way to report this. also, the app does not let drivers mark their last ride on their app as it will still assign rides to them....
