Ridesharing outfit Sidecar announced that the company will end its current payment system where riders could “donate” but not outright pay for a ride. Instead, riders must now pay a minimum amount as determined by Sidecar. The system was apt for abuse as those who shared a ride with a driver could simply choose not to pay after the ride is given. The move comes as Sidecar is fiercely competing against Uber and Lyft for customers. In response, Lyft announced that it too will dispense with the “donation” method and obligate riders to pay a minimum amount. Sidecar believes that drivers would be more willing to drive farther and more frequently if there was a concrete way they could receive reimbursement for related expenses. The changes will apply only for California customers.
