sure, but this why ownership as a concept is actually quite nice - i can decide right now to do something with my car. i don't need to plan ahead. i am not dependent on anybody else. i gladly pay for that luxury.
The ability to book the type of car I need (van to move something large, ute to deliver dirt/gravel, tiny car to commute, 4WD for a family camping trip) as the default way of thinking can't come soon enough for me.
Actually, it is quite a hassle to have to operate on the airline's schedule rather than on my own, not to mention having to make travel arrangements weeks in advance. It's just that owning and operating an airplane myself is too expensive for me. Since moving to Boston, so is owning a car. That said, I am definitely not planning to switch to rental bicycles.
I have a question for you. How many years after the introduction of the gasoline powered automobile did it take before horse-drawn vehicles became illegal on the roads?
Near where I live (eastern Pennsylvania, USA) one still encounters a horse-and-buggy occasionally, especially near Amish areas. And a few roads (interstates and limited access highways) are specifically posted for motor vehicles only.
I posit that there will be a LONG period in which manually operated cars will share the road with self-driving cars.
what if i enjoy driving a car? what about motorcycles? you want to ban them too? oldtimers, just for spite? sugar drinks? sweets? alcohol? drugs?
should i book a car for the weekend? a last minute shopping tour? etc. etc. etc.
As others have mentioned, the car-sharing model works best in urban areas, and no one is suggesting that we ban individuals from owning cars. But I will also add that we have spent the last 100 years building infrastructure and public spaces to accommodate for a car-centric society, but this has had a negative impact on people who prefer other forms of transportation. Public transportation is severely underfunded and inadequate in most places, pedestrians and bikers are getting mowed down by reckless drivers, tons of public land is being poorly utilized as parking space, and our air is getting polluted to unprecedented levels. Your "peace of mind" comes at a high cost to the rest of society. Autonomous cars are not a silver bullet for all of these problems by any means, but they can go a long way in getting us to a better place with most of these issues.
