Finding and vetting drivers will be the slightly harder task...
No, they integrated it so that Maps becomes the go-to point for users when they need a ride. That way, Google can snatch those users away when Waymo becomes available. The internet nowadays is all about being the "gatekeeper", and Google just wants to stay in that role.
I can hardly imagine taking the human drivers out of the equation will be that profitable. Right now, those drivers also do the labor intensive part of maintaining the fleet (gas/power, cleaning, repairs etc.). That part will stay with uber, lyft, google etc.
I think manufacturing cost is a much stronger driver of shitty reliability than repairs being a profit center. After all, in the US dealer system the manufacturer isn't getting the profits, the dealer is.

Keeping complex systems like that running constantly is difficult and expensive. It also wears said systems out faster and increases capital costs.
This is a good point. When you purchase capital equipment, your incentive is to keep it utilized as much as possible to maximize ROI. That means you're going to want your self-driving car fleet parked as little as possible because when they're parked, they're not making you money. Now that the cars are driven far more than regular passenger cars, their maintenance needs go up.
So either these cars will need to be built to the reliability needs of over-the-road trucks, which will greatly increase costs, or their maintenance will have to be more frequent, which is even more expensive.
Pardon my ignorance, but why doesn't the manufacturer open a dealership then?
As you pointed out, this is a very fickle (price sensitive) group. Anecdata-ly, I can point to many who prioritize Lyft based entirely on personal price comparison history.
Google Ventures invested a large amount in Uber as well – I think they owned something like 5% last time I looked.
