Ugh. Thanks for letting us know, Bob. I hope the rider’s okay.
I ride through there frequently, and it’s a tricky intersection. Speeds can be high, sightlines low, and people generally don’t expect bikes around there. Definitely a “take the lane” sort of place. (And it’s also super important to pay attention to the lights, esp. if you’re on the sidewalk. Everyone gets a turning arrow, which can lead to unexpected pedestrian crossing priorities/conflicts).
Right now, the WABA Crash Reporter is only set up to take reports from those directly involved. If that changes, I’ll post up here (frankly, I’ve not completely thought through the cost/benefits of adding witness reports).
