The ride-sharing firm Uber is set to let its passengers hail self-driving cars.
The move will begin in Pittsburgh, Pennsylvania as part of a tie-up in Volvo.
According to Bloomberg, the vehicles will be supervised by a driver for the trial runs.
A spokeswoman for the firm told the BBC: “Starting later this month, Uber will allow customers in downtown Pittsburgh to summon self-driving cars from their phones, crossing an important milestone that no automotive or technology company has yet achieved.
“In Pittsburgh, customers will request cars the normal way, via Uber’s app, and will be paired with a driverless car at random. Trips will be free for the time being, rather than the standard local rate of $1.30 [£0.98] per mile.”
