Weird coincidence; last night I was car-doored on my bike ride home from work. I had my lights on and flashing, I was paying attention, and a guy opened his car door about 20 feet in front of me, way too close for me to respond. Even if you're careful, the people around you aren't always going to be. My helmet saved me a pretty serious head injury last night.
