This comes out to roughly 1 parking ticket per vehicle every 2 months.

Not something to do nothing about, but also not especially surprising for a taxi service in SF, imho. It would be interesting to see the numbers for Uber/Lyft/taxi drivers.

> a horrendously bad driver that has injured 117 people and killed two.

This is conflating "a Waymo vehicle was one of the involved vehicles" with "the Waymo software was responsible for the crash/injury/fatality".

Perhaps it was responsible for some the injuries (I'm always open to the possibility); but unlike with some of Uber's and Tesla's infamous fatalities, the Waymo fatalities were determined to not be the fault of the software:

   The self-driving Waymo car was among six vehicles struck when a fast-moving vehicle slammed into a line of car stopped at a traffic light at the corner of 6th and Harrison Streets, about a mile south of the city’s famed Union Square, according to NBC.

  While the Waymo was empty, a passenger in one of the other struck vehicles and a dog were killed. Several others also suffered injuries, according to the San Francisco Police Department.

  According to authorities, the Waymo vehicle, which was driving with no passengers, was preparing to make a right turn into a parking lot when it was struck from behind by a motorcycle. The Waymo vehicle had slowed for pedestrians blocking its path and was signaling its turn at the time of the incident.

  Witnesses reported that the motorcyclist did not adjust speed appropriately and collided with the rear of the Waymo. A human-driven vehicle in the adjacent lane then struck the motorcyclist before fleeing the scene.

  Emergency responders were notified, and the motorcyclist was transported to a local hospital, where he later succumbed to his injuries. Waymo has stated they are cooperating with law enforcement and have provided surveillance footage to assist in the investigation.
