Countdown until we learn that Waymo is similar to those Amazon stores where the self-driving cars are actually controlled by offices full of people who are playing a variation of Mario Kart in order to get us to our destinations.
Marty Fouts@Alice Waymo is operating under a program from CAL DMV that sets three classes of vehicles for them. Some areas require backup drivers in the vehicle, most require remote monitoring of the vehicle, while none yet allow unsupervised driving as far as I know. San Francisco is remotely monitored but the recent addition of Sunnyvale still requires drivers in the car. However Waymo does not remotely operate the vehicles unless there is an emergency.
@MartyFouts Thank you for the heads up about Sunnyvale! I feel like being stuck in a car with a person who isn't even driving who has ALL of the time in the world to chat would be even worse than your average Uber driver who's at least partially busy driving while trying to make awkward small talk.
@Alice In theory the emergency driver is supposed to monitor the vehicle and be able to take control immediately if there is a problem. In practice something called automation inattention means humans are bad at that.
