By Christina Farr SAN FRANCISCO (Reuters) – When Jonathan Lyens ordered a car on Uber's mobile app, the driver took one look at his service animal and considered taking off. "'I don't usually pick up dogs,'" Lyens, who is legally blind, recalled the driver saying. "This driver seemed to have no awareness of disability rights laws." San Francisco regulators and the National Federation of the Blind are looking into claims that drivers for the rides-on-demand service have refused to ferry people with service animals. Michael Hingson, a member of the California board of directors for the federation who is also legally blind, described the problem as "systemic." "It's a breach of civil rights," he told Reuters.
