I have what I call my Steiney sense, I am on high alert for anything that looks wrong. Most riders have this if they ride for long, only way to stay alive on the street. I usually see what's coming at me long before it becomes an acute danger and take evasive action. Used to be I'd do this a few time a year, now it's a few time a week during riding season. I am a bit worried, I'm starting to get surprised by folks imperiling me that I didn't see coming. Bound to happen with the rise of idiot driving. Nothing I can't handle, but a worry nonetheless. Like I said, phones, lots of them.
Agreed. There are also riding techniques such as lane choice and position, route selection, and so forth that reduce risk and avoid bad situations before they pop up. For example, left-turning vehicles are a risk, so when possible on a 4-lane road I will time things so I go through an intersection in the right lane next to a car in the left lane, guarding me from left-turners.
