Uber offers on-demand rides in vehicles that vary in their swankiness. Fares on its lower-priced UberX option are about to go up with a “Safe Rides” fee tacked on to your receipt. The company said in a Thursday night blog post that the $1 fee is its way of demonstrating “continued commitment to safety.” The $1 per ride goes toward background checks, DMV checks, driver safety education, insurance, and the app’s safety features.
