Yesterday I saw a cyclist breeze through a red light, turn right from the left lane to go the wrong way down a high-traffic one-way street, all at an intersection with two police cadets on each corner.

Police cadets wait until the last second before clearing pedestrian traffic for a speeding ambulance
And when an ambulance needed to get through, it was telling that eight police cadets weren’t enough to clear an intersection for it in advance.

Cadets stop pedestrians from crossing on a flashing hand (in one direction only)
But thanks for making sure people didn’t accidentally cross the street on a green light. That might have been dangerous.
