Fun fact, if they are using foreign workers at all, however briefly, they are likely in violation of state law in multiple states.
HOWEVER:
It is entirely possible that some back room deals were made, and possibly laws put on the books in the states they've rolled out in.
I suspect more will come from this, eventually, especially if waymo is involved in accidents that involve insurance claims, injuries, or deaths in one of those states.
Wouldn't it be risky to do that? This is a multi-billion dollar gamble being executed in front of the public, egregiously breaking the law or making back-room deals both risk extreme negative public reaction if exposed.
We know that eventually a self-driving car will hit somebody and kill them. Waymo and other companies are prepared for that.
what state law would they be violating?
IIRC from when Waymo discussed this previously, the remote people don't drive the car, they issue instructions to the autonomous driver. If that's the case they shouldn't need a driving licence.
