Well hey if it somehow costs less than then I spend on car ownership in a year, then sure! All just depends on how much my time's worth/how much these services charge if/when they come around. But right now the sum total of rides per year, whatever the cost model, would basically have to be sub $1000 per year to make sense for me. Cheaper if I end up making more money as time goes on. If scale and commoditization can accomplish that then I'll happily embrace a new golden age of transportation. As for the rest, keep in mind we're comparing renting an autonomous car vs owning an autonomous car, not renting an autonomous car vs driving. So the actual rides are equivalent. The time difference is me getting in my car and telling it where to go vs me hailing a car, waiting 5-10 minutes for it to arrive (where my capacity to do any meaningful work is basically nil) and then tell it where to go, a minimum of 3 times a day. Maybe up to 12 times a day on a busy day. That's not an insignificant time loss over the medium/long term. Granted it's all hypothetical and the actual value of the time lost would be highly situational, but it would be one of those small daily time-sucking inefficiencies, like walking into the other room to get paper towels as opposed to just putting a roll in the kitchen. When you do them every day, those add up.
