Waymo, Alphabet's autonomous car unit, is ramping up plans to deploy a fleet of self-driving minivans as the company pushes toward the launch of a ride-hailing service later this year. Waymo has finalized an order for thousands of self-driving Chrysler Pacifica hybrid minivans. The company is not saying exactly how many modified Pacifica vehicles that Fiat Chrysler will supply, but a spokesperson said it will be fewer than 10,000 minivans.
