Yellow police tape and a blue glove from a first responder at the northwesteast corner of the intersection of Park Presidio and Balboa

We still don't know the cause of the fatal accident that killed 83-year-old Marina Vafiadis Tuesday night.

What we do know is that the traffic signals at almost all the intersections on the 19th Avenue/Park Presidio/CA State Highway 1 corridor would be more appropriate in Mayberry R.F.D. than a well-travelled route to the Golden Gate Bridge.

Changes are coming, slowly but surely.

Slowly.

Read some lively comments and decide what's the cause of the inordinate delay.

Too much community input? Can there be such a thing? State vs. local conflict? Inertia?

Who will be the next fatality on this stretch of road this year?

Tick tock.
