Here’s what not to do.
The traffic light turns green. Initially it looks like all the drivers are either going straight or left. We filter up on the right. At the same time, a driver signals right and begins the turn. The rider behind me calls out the right turn and grabs all the brakes. And I yell, hoping this will get her attention to stop. It is hard to tell from the video or our memories, but it doesn’t look like the car stopped.
I have been through this intersection many many times. I have commuting over ten years. And if everyone is signaling straight I filter up and continue on. But not any more. We have decided to take the lane and get in line. This might slow traffic a minor bit. But no more chances for right hooks.
