How much cheaper will it be to hail a driverless taxi than to own a car in the future? A lot, according to the financial services firm UBS.
 UBS forecasts that taking “robotaxis”—i.e., self-driving taxis—will be half as expensive per kilometer as owning a car in the future. The firm expects to see widespread adoption of robotaxis in urban areas starting around 2030. It estimates that the typical household could save €5,000 a year (about $5,875) by switching to robotaxis in the future.
 UBS thinks the shift toward electric vehicles alone will reduce the fees robotaxi companies charge by 15%-20%. It expects the “robo” part—aka, getting rid of human drivers—to cut user costs by another 25%. UBS is also counting on competition to drive down prices.
