Self-driving start-up backed by Toyota has transformed its robo-taxi fleet into a driverless grocery delivery service last week. The move came in response to the ongoing lockdown in California and the heightened need for essential goods amid the Coronavirus pandemic. The start-up, Pony.ai, is partnering with e-commerce site Yamibuy on the initiative and its fleet consists of 10 self-driving electric Hyundai Konas. The outfit had been participating in a robo-taxi pilot in the city of Irvine, California, since November 2019 but was forced to ground its fleet in March owing to the state's lockdown orders. Now the vehicles will run delivery trips from Yamibuy's distribution center to residences, condos and apartment complexes in Irvine.
