But also those busses wouldn't be able to come to your door, or drop you off directly at your destination.
So I don't think I'm describing efficient public transport. I'm describing something like the platonic ideal of taxis in a dense city, but without the huge number of drivers.
But now imagine if every passenger instead took an individual car? That would require a lot of cars.
Yes, an individual car is more comfortable if you can afford it and if not too many people have one (otherwise you need big big roads to avoid traffic jams). But really my ideal is closer to metros/trams than taxis.

Right, that's the main downside, but there's a lot of areas where they'd fit.
Then of course they can be used together. In my city there is a system of rental cars that you leave at different stops: you have a card and can just take the car if it's there. The car doesn't come to you, but still it's a pretty good solution I think.
Anyway, autonomous cars have to get reliable before they can actually be used with public transports, I guess.
I don't go on a lot of long-term trips, but if I did that would still be a reason to get one car for a household instead of multiple. For rarer trips I would be happy to have a rental drive itself to my house.
If you mean day trips, then none of those issues are notable with a competent self-driving fleet except "one bag", but I don't think I've ever needed more than one bag for a day trip...
