I bike to work 3-4 days a week and have a close call nearly *every day*. Last week, the closest call was a car that drifted into the bike lane directly in front of me while the driver obliviously texted on her phone. Sure hope that text was important enough to almost kill me.
One of the hardest things about being a cyclist is dealing with the nagging feeling that a serious crash is inevitable. Because you can indeed do everything "right" and it still does not matter.
