How do you get to 20-30% margins off of $1/mi costs? Uber and Lyft are already <$1/mi for pooled services and around $1-1.50/mi for non-pooled services in low cost markets. Price competition should make anything beyond classic transportation margins of (negative) - ~5% standard for any self-driving taxi service. 20-30% gross margins might be standard but operating margins at that level seem like a pipe dream.

They also mentioned data monetization as an unspecified portion of those 20-30% margins. Robotaxis will gather a lot of data, around 4 terabytes a day. Enough to hypothetically run a real time virtual simulation of a city, if 1000s of sensor riddled robots are all prowling the streets, seeing, recognizing and classifying everything. I can think of all kinds of ways to monetize data like that, both good and terrible.

The robotaxi fleets only need so many cars, and they could always start off selling vehicles at a larger margin to those that really want them.

They're throwing away money if they never sell the cars.
