A 76-year-old driver was arrested this week after fatally striking a pedestrian in Chinatown, adding another name to San Francisco's grim and growing list of traffic deaths.

Details are still emerging, but here's what we know: a person is dead, a driver is in custody, and one of the city's most walkable, densely packed neighborhoods has once again proven to be one of its most dangerous for people on foot.

Chinatown's streets are narrow, crowded, and full of elderly residents who rely on walking as their primary mode of transportation. This isn't news to anyone who's spent five minutes there. And yet, meaningful infrastructure improvements — better crosswalks, more visible signage, traffic calming measures that actually calm traffic — remain perpetually stuck in the planning phase or buried under layers of bureaucratic review.

San Francisco loves to talk about Vision Zero, the city's pledge to eliminate traffic deaths by 2024. That deadline came and went. Deaths continued. The program has consumed tens of millions in taxpayer dollars, produced plenty of reports and consultant fees, but the people who walk these streets are still dying.

This isn't about demonizing elderly drivers. It's about asking uncomfortable questions. Are we doing enough to ensure drivers of all ages are fit to be behind the wheel? Are we spending Vision Zero money on interventions that actually work, or on feel-good bureaucratic busywork? And why does a neighborhood as historically significant and pedestrian-heavy as Chinatown still lack the basic protections its residents deserve?

Every one of these fatalities represents a failure — not just of an individual driver, but of a city government that treats safety as a slogan rather than a mandate. Chinatown's residents pay taxes too. They deserve more than thoughts, condolences, and another round of "community engagement sessions" that lead nowhere.

Do something. Or at least stop pretending you're trying.
