I live in a mid sized town (200k) and we have had three unrelated motorcyle fatalities this week. From what I understand all three were experienced riders. Definitely makes me be extra cautious out there.
Anyone who rides and does not ALWAYS ride defensively is on borrowed time, in my opinion. You have to be constantly on the alert and anticipate someone in a car/truck is going to do something stupid to hurt you. Being aware of your surroundings will hopefully give you some time to react and avoid being a statistic. It may not always work, but it can certainly help. Many years ago I was in an accident that cost me a week in the hospital so I speak from experience.
As the old saying goes, anyone who rides has either been in an accident or will be at some point in their life. Just do your best to try to reduce the chance it will happen to you.
