> The comfort of having my own vehicle that is set to my own preference and loaded with my stuff
From this statement it seems like you either don't work in a city, or live outside of a large metropolitan area. There's little chance you're leaving stuff in your car routinely in a large city and not having it stolen. This isn't meant as an insult, but I think it means you're not in the target demographic for a shared self-driving car service.
"Loaded with my stuff" doesn't mean all of my favorite consumer electronics left in the open in the passenger's seat.
My behavior barely changed between living a mile away from the nearest person to parking daily in SF. Yes if I have something valuable in the cabin I'll put it in the trunk when I leave the car, but that's it.
