On a particular day within the last 10 years, this happened to me twice on a routine trip from Cleveland to Dahlonega, Georgia. The first one, a car pulled out from the right and stopped, forcing me to cross the center line. This was on a state highway, probably traveling at 60 mph. In retrospect, I was too close to the vehicle in front of me, making me more or less invisible to the driver waiting at the stop sign. Safe following distance isn't always enough. Once in Dahlonega, driving maybe 30-40 mph, a large pickup truck came out of a business on my left turning onto the road in my lane just as I arrived at the scene of the would be crash. He stopped leaving me just enough room to squeak by without hitting the curb. That was two very close calls within about 30 minutes of each other in a place with more motorcycles on the road than anywhere else in the USA that I have been. I've had close calls and crashes, but never anything in succession like that.
