I think they rather like the idea of having someone else bear the burden of maintenance. You buy yourself a driverless car, you drive to work, and once you are there you send your car to drive for uber, then in the evening it comes to pick you up and take you home…
It’s a nice fantasy - but currently driverless cars struggle with bad weather, get horribly confused by snow and I cannot imagine how they would easily deal with the pax never being at the pickup site or damaging the interior.
