this dystopic scene of identical robocars clogging an entire block to carry maaaybe 1/4 of a busload of people, was posted by a waymo employee who thought it made his company look good.

A row of identical white cars with black spinning sensors on the top stretches down a block as far as the eye can see. There is also one further down that appears to block the bike lane.

Today, we’re launching a new campaign to make the Wiggle–San Francisco’s premier east/west bike artery–safer for all. If you want to see the city install safe pedestrian and bike infrastructure like it, use this 1 click link to send an email to SFMTA- tinyurl.com/SSRwiggle/

The Wiggle connects the Mission and SOMA to Haight-Ashbury and the entire west side. Everyone who bikes in SF relies on it, and yet with just two exceptions, every part prioritizes cars over bikes and pedestrians.

A sign in the median saying “The Wiggle Yield to Peds & Bikes” with a Muni train in the background
