The other thing to consider is large scale autonomous driving in itself is a lie. It's going to require a significant about of momentum to force it. To do this date no one is doing large scale full-self driving or even Level 3 driving. They're not because they can't break through all the barriers (regulatory, liability, etc).
I disagree with the above. No one is doing large-scale FSD because nobody is there yet. It has turned out to be more difficult than people thought. That does not mean that the idea is a lie or is impossible. It just means it will take longer than expected.
As for regulatory and liability issues, these are non-issues. Once the hardware and software exist and demonstrate that the system is safer than a human driver by some reasonable amount, the insurance companies will be all on board and the regulators will follow. As for liability, the cost of insurance will be priced into the car. Easy peasy.
How many driverless cars will you be able to buy? Will you be able to own a waymo? Tesla is the only one in this field at present.
Waymo's business model is not to sell cars to consumers. It is to license the technology to car makers. If Waymo cracks the FSD nut before Tesla (and I think they're ahead, partly because they're not limiting themselves to the sensors built into 2018 cars) any car company that wants to enter the FSD market will be able to license their technology, and Tesla will have to do the same or be late to the party.
