I thought Weymo's were supposed to be "supervised" by humans in the Philippines. Maybe driving in circles in the suburbs and driving into flood waters happens only when the cars are out of mobile data range? Did Weymo pay their mobile phone bill? Does the (somewhat) autonomous system on the car decide when to flag a human for help? I would have expected a human to be watching all the time. Are they experiencing labor problems in the Philippines? Maybe Weymo doesn't want to pay their remote operators as much as the remote operators want to get paid?

Your assumption that Waymos are "(somewhat) autonomous" is wrong, which is why your questions and conclusion don't make any sense
