Waymo and their ilk are trying to replace public transport with their own for-profit self interests. When their cars kill occupants, or pedestrians, or other road users, or generally become a nuisance, driving slowly or unpredictably or violating laws then why should anyone accept it?
They might claim safety but they have an obvious conflict of interest in being truthful. While I trust Waymo more for transparency that Tesla, the reality is all of these things should be held to regulatory scrutiny and independent research and there should be a statutory obligation to provide data that makes independent appraisal possible. And those appraisals should become published safety ratings for the service based on things such as 1) safety for occupants, pedestrians and other road users - not just road accidents, but robberies, attacks, 2) making progress, i.e not dawdling or driving erratically, 3) adherence to the law, 4) public services, i.e.
In addition, cities and governments should limit the fleet size of these services, tax them to fund public transport, compel non-discrimination of service, and amend road traffic laws to prosecute & criminally charge companies and board members if they are found negligent. And maybe, just maybe with all that in place then fatalities might be deemed acceptable, counterbalanced by the reputation and criminal liability these companies are under.
