It may not be for you, or me for that matter, I like to drive.
Though, for most, the basic economic equation will likely lean toward people preferring a private chauffeur-service over ownership. Particularly when the Robotaxi could save the user money, when all ownership costs (parking, time, hassle) are weighed.
Pretty much all persons living in an apartment or dense urban environment with challenging or costly parking hassles will jump at the chance to rid themselves of the headaches that come with car ownership.
Folks in the suburbs and rural areas are more likely to prefer ownership. Though anyone wanting to use their garage and driveway space for something other than parking their car while not in use (a significant portion of the time) might see some advantages to Robotaxi only, or, reducing their household from a two or more car family, to a single car + Robotaxi scenario.
