Waymo, with over 300 driverless vehicles in San Francisco, received 589 parking tickets in 2020.The parking citations totaled $65,065 in fines and were for various violations such as blocking traffic and parking in prohibited areas.Waymo cars sometimes stop in commercial loading zones or park briefly between trips, facing the same trade-offs as human drivers.Waymo is working on addressing the issue, but a solution may only come when all cars are fully autonomous.
