It seems possible that people in the Philippines providing advice to Waymo vehicles in the US get some training on US road signage, traffic regulations, etc. (I can't see how it would make any sense for Waymo to pay people to do this and not give them the information they need to do it reasonably well, since the whole point is for them to handle difficult cases.)

And it would be difficult for whatever training Waymo provides to its employees to be less stringent than the lax license requirements of most US states.
