Waymo is lobbying for a bill that would legalize robotaxis in the District of Columbia. Uber opposes the bill, arguing it would displace human drivers. The bill was up for debate during a marathon hearing today (I just checked; it’s still going), but don’t expect a vote any time soon. As TechCrunch notes, the bill is exposing fractures in the Waymo-Uber relationship that could deepen as more big cities confront similar debates.
