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&#x27;t trust drivers that much.<p>The only true solution is separated bike paths, but that doesn&#x27;t seem likely to happen in the US.
