Presumably because the cars would be substantially more expensive than an ordinary car due to all the high tech packed into them. Assuming that the components of the car have a finite lifetime, it might be possible that the overall cost is so much significantly more than a normal car that they won't be able to compete with a human driven solution like Uber.

Does anyone have any actual statistics/calculations on this sort of thing?

I have no good collections of statistics to share but the price of lidar seems to be dropping.
