I’m certain all of us are likely better than good defensive drivers on two wheels – we have to be to stay out of trouble. Although probably not the case with the neighbor turning in front of the rider, cell phone use is by far the single greatest hazard developed in my time riding going back to the early 1970’s. It’s far more difficult to anticipate what drivers will do now than it used to be - cages rolling, not always completely stopping at traffic lights and stop signs, running stop signs, never looking up where we can make eye contact because they’re texting or reading their phones, wandering into our lane, etc. There are many factors involved that must be overcome, but I don’t intend to stop riding because of them. Maybe if I were the rider who collided with the neighbor I’d change my opinion, but in my forty years riding that hasn’t happened yet, but you just never know when it's going to be your turn.
