Waymo cars don't have a driver, and they don't let a passenger take over driving. That's level 4: https://www.sae.org/binaries/content/assets/cm/content/blog/sa

  Perhaps it straddles the line between 3 and 4. I don't see much of a distinction between the passenger taking over, and a first responder taking over. Would Waymo put cars on the road that don't have pedals and a steering wheel if it were cheaper to do so? I don't think they would. I think they want a backup in case the car has to be driven by a human.

    No, it's very clearly level 4. Here's how you can tell so that you don't get confused as easily in future. Level 3 cars can require the occupant to drive the vehicle, "When the feature requests: You must drive the car". Waymo even offers service to people who cannot drive whether that's legally (they aren't licensed) or physically (blind people can use Waymo but can't drive a car). They are simply not required to take over driving.

  They have remote operators that the car can request help from. That's level 3.

    It's been reported that the remote operators can't drive the car, they can only guide the decision-making process.

      > guide the decision-making process What does it mean exactly? Because this can mean everything really. I mean you could guide decision making process by "now press break, now reverse and...", is it still driving?
