Christopher White, the current head of the San Francisco Bicycle Coalition, got his start in advocacy 20 years ago when an inattentive driver turned left in front of him on Arguello, sending him careening into the windshield. Since then, Arguello has remained on San Francisco's high-injury network. A teenager was badly injured there in 2022. Cyclist Ethan Boyes was killed on Arguello by a drunk driver in 2023.
