My point is that as bicyclists, we are responsible for our own safety, regardless of laws. As an example, drivers are required by law to stop at stop signs, but sometimes they don't, and I need to be on the lookout for that so I don't get t-boned. In the OP's instance, luckily she didn't experience any catastrophic injuries (thank goodness!).
Let's say I get t-boned at an intersection and end up paralyzed because I assumed a car driver would stop at the stop sign and he didn't. From a legal standpoint, yeah, it's his fault I got hit. But from an injury standpoint, placing blame doesn't really help me much...the damage is done. So what, if anything, could I have done to prevent it? Would the situation have turned out differently if I assumed that the driver was texting, or pissed because he just found out his wife is cheating on him, or distracted because he's thinking about the meeting he's about to have with his boss, or drunk, or asleep at the wheel? Possibly, because I would likely slow down at the intersection until it was painfully obvious that the car was coming to a stop. (On a related note, when I'm driving my car, I make it a point to actively wave a rider or pedestrian on, so they know I see them and it's safe to go. But as a driver, I'm sure I've done a few stupid things or overlooked a pedestrian once in a while, too.)
I never wanted to get into an argument about laws or the legality of opening a car door without looking to see if there's a bicyclist coming. I simply wanted to put some thoughts into the thread about thinking and riding proactively/defensively to avoid getting hurt, because drivers break laws and do stupid things all the time. We don't want to forget that.
