As automated vehicles such as robotaxis become more common on American streets, transit systems are debating whether to go driverless as well. Despite rail being safer than road travel, most U.S. systems still use human operators. Automation has lagged behind Europe, but some cities are now considering it. Washington, D.C., is looking to fully automate its Metro Red Line, and Los Angeles plans a new automated track through the Santa Monica Mountains. Honolulu already operates a driverless train system. The debate centers on safety and cost, with unions resisting automation due to job concerns. Proponents argue automation could enhance safety and efficiency.
