Right in front of my building this morning I saw the aftermath of a collision between a bike and a car.....generally not a good outcome for the cyclist.
Based on the damage to the front wheel of the bike, the passenger-side car door, and where he was lying face-down in the street, I expertly deduced that he was motoring down the sidewalk and saw a red light and a "Walk" sign, giving him the ok to cruise on across the pedestrian crosswalk. What he didn't notice was the SUV turning right on red into his path.
Two faults here: 1, the lady in the SUV should have made sure the pedestrian crosswalk was clear before she turned right on red. 2, bikes shouldn't be in the pedestrian sidewalks or crosswalks....they are supposed to be operated in the street.
I didn't see a helmet and the guy was wearing shorts and a T-shirt, but if you are going to operate a bike unsafely in traffic, I guess the center of a medical school campus and like 3 major research hospitals full of doctors and nurses on the way to work is where you'd want to do it.
I hope he's ok, the ambulance arrived maybe 10 minutes after I walked by so it had just happened.
