Situational awareness only helps if you have options. If I am biking at 15 mph, every car around me is still going at triple my speed. If there were a car or two passing me each minute, then I could slow down and pull over for each one. When there is a constant stream of cars, I would need to trust every one of them to notice me. I don't trust drivers that much. The only true solution is separated bike paths, but that doesn't seem likely to happen in the US.
