After investigating about 120 claims of sexual harassment or assault from Uber and Lyft drivers, Laurel Simes and her team at Levin Simes Abrams in San Francisco say they have uncovered an unsettling pattern among both companies’ drivers.

First, they say, a driver might start asking inappropriate questions about sexual matters. Sometimes it’s unwanted advances like, “Oh you look so nice tonight. Do you have a boyfriend?” Simes said. Other times, she says drivers wait until a rider gets out of their car to lunge and grope at them.
