It is theoretically possible, sure. I'm trying to imagine a nontrivial number of people who currently own a private vehicle selling that vehicle to rely on prebooking both of their daily commuting trips with a flexibly-priced mode of transportation to save money. As a datapoint, I know many people who regularly take car services like Uber, but I don't know of anyone who actually sold their car to rely exclusively on a car service to commute. Perhaps if driverless cars halve the price of car service it might start to happen? I'm not saying it is not theoretically possible that driverless cars will reduce car ownership, I am saying that I am skeptical of the weak arguments and minimal evidence provided thus far for such a claim.
