It’s interesting that they only have 70 people for this - I can understand the outside the US ones for nighttime assistance and they need to be able to scale for other countries too in the future.
What I’m still wondering is what is limiting the scaling for Waymo - just cars or also the sensor systems? They’ve had their new test vehicles in SF for a while but I still think that most customers only get their Jaguars right now (and still limited on highway driving to specific customers in the Bay Area).
