Waymo, Alphabet’s robotaxi service, is steadily making its way to major cities across the country. Now, it is offering some of its most loyal riders a new membership program. The program is called Waymo Premier. It is invite-only for now and is initially being offered to select riders in San Francisco, Los Angeles, and Phoenix. The $29.99-a-month program gives members several perks, including priority pickups, 10% Waymo Cash back on every trip, early access to Waymo in new cities, and up to five free cancellations a month. “As we scale and bring our fully autonomous ride-hailing service to more people across the globe, we continue to refine the Waymo experience and deliver more for our riders,” the company said in a blog post. “You spoke, and we listened to how we can offer an even more elevated experience for you, our top riders.” Waymo says it plans to offer Premier to more riders in more cities in the future. The new subscription plan comes as Waymo is quickly expanding its fleet and coverage area. Last month, Waymo said its service area would soon cover more than 1,400 square miles across 11 cities. The company bragged that its coverage area will eventually be larger than the entire state of Rhode Island, which is roughly 1,200 square miles. The company also has plans to expand internationally, starting with London and Tokyo.
