Every right hook I've encountered was committed by a vehicle that passed me, then turned in front of me. Those are the most difficult to avoid because it's sheer negligence. The driver put me into their blind spot, not the other way around.

It's also why I don't trust or relax around dedicated bike lanes on city streets, especially between traffic to the left and parking to the right. Between the door zone and right hooks, it's an accident waiting to happen.

I'm usually prepared to brake hard when forced to ride those bike lanes, whenever approaching a driveway or intersection.

But both of my close calls Tuesday were drivers turning left across my path. The first was a pickup (why is it always pickups?) driver who jumped a protected walk signal. He looked right at me the whole time and kept turning in tighter toward me. He saw me. He just decided his turn was more important than the traffic lights or common courtesy. I had a front light flashing but it wouldn't make any difference with aggressive, hostile drivers.

The second was a distracted woman in a van. She stopped her turn as soon as she looked up and noticed me, and rolled down the window to apologize. I didn't ask her whether my light made any difference to her.

I'll keep running daylight strobes anyway. Costs me nothing. And a few drivers and other folks have said it helps to see us better.
