I think anyone who says they feel safe around traffic is deluding themselves. Anytime you mix cars and bikes there's the potential for bad things to happen and the guy/gal on the bike is going to lose.
I feel far safer cycling in PDX then I do driving. In fact, I worry a lot more about my better half's car commute. I've also found that most of those who emphasize the perceived risk of cycling (often the car/truck wins physics canard) are
sanguine about their motoring. Given the 33-40K per year killed by motor vehicles in the USA this strikes me as irrational.
To address the OP:
*Being cut off by an impatient driver. I guess this fits under over-taken.
*Having a driver pull out in front of me (e.g. from a driveway or stop) because they misjudge my speed.
