I would alsopoint out that Uber and Lyft drivers trolling for rides in major cities are also major problems for traffic. It is not just a Waymo problem.

A trip to NY city will provide ample evidence of this as more than half the uber and Lyft cars travel around the city empty looking to capture a rider.

Most of the uber and Lyft vehicles actually burn gasoline as opposed to an EV contributing to ground level pollution in the city. The same can be said for Taxis in NY. Accountability is an issue but at least there is significant data associated with Waymo and other driverless cars including reams of video. Though some Driver operated cars have video and sensor data it is not as widely available and depends on the driver and the age of the vehicle.
