I wonder why the cost is high. Maybe to discourage folks who want a service competitive with a human driver?
I read somewhere that each vehicle cost $250k because of all the hardware
Surely, though, the cost of operation has little to do with the cost of rides? Google has poured billions into the project. A few dollars per ride isn't helping their accountants sleep any better.
Hardware costs are dropping pretty fast. Lidar is already an order of magnitude cheaper and compute benefits from Moore's Law.
