Tonight I spent one hour at the corner of Cesar Chavez & Guerrero St counting driverless cars.

Between 5-6pm, I counted 27 driverless cars, but only 1 appeared to have a passenger.

During rush hour in #SanFrancisco, 96% of the Waymos, Cruises, and Xoops on this busy street were empty!

edit: driverless cars can operate 24/7 in SF, but I've been informed that some are only taking passengers during certain hours (ie 9pm-5am). So the cars I saw today were probably not accepting any paid rides.
