The visual difference that turning radius makes. The wide turning radius on the street allows cars to make faster turns and makes the crossing distance about 20 feet longer-- two things that make this side of the the intersection more dangerous for pedestrians to cross a busy road. The left side uses a small turning radius.
@markstos Another reason to #DecriminalizeJaywalking; people want to cross where the crossing distances are shorter. That is often NOT at the crosswalk.
