Especially since I ride my bike to campus every day, and have to watch out for my own skin. If I don't automatically assume people don't know I'm there/see me, they would be hitting me.
that's not really fair since driving, even in heavy activity, takes less than half the concentration associated with that test.
but more caution definitely needs to be exercised; every day i see cars blow by crosswalks even when pedestrians have been standing there trying to cross for 5+ seconds
