Waymo might very well be missing specific kinds of data (e.g more incidents/accidents, near-collisions etc)

Also, Uber’s data might be useful for eval, not training (e.g « here is how Waymo would behave vs human drivers therefore it is safer »)

Accidents and near-collisions are exactly the kind of scenarios perfect for simulation. You don't test them out in the real world and risk injuries/deaths. You need to have confidence they're handled before you deploy.

Again, how do you know you've handled it correctly without ground truth? Simulation without ground truth is a garbage in garbage out situation.
