Waymo privatized another public street:
Chanel approaching 4th, San Francisco
Possibly queued for a Billie Eilish show at Chase Center ~half mile away.
The light rail train on 4th seen passing in front of this roboherd has more passenger capacity than all of them combined.

Like Uber, AVs have the upside of reducing parking demand. Downside: big increase in Vehicle Miles Traveled and traffic -- including lots of miles driving empty

Trump Administration is to propose a massive cut in federal transit funding as part of 2026 transport legislation.
This proposal would decimate the nation's transit systems, while not actually solving the revenue problem federal transportation funding faces.
