Of course, because emergency workers would love nothing more than arrive to a location, pull up their phone, open the Block-a-Car app, manually draw a fence with touch controls, then do it ten more times because no self driving constructor wanted to standardise on a single app. While, of course, a house is burning, a person is dying in the streets, etc. No. The alert is the lights and sirens, and any driverless car unable to respond to that signal should be banned from roads. Emergency services have other things to do than draw a geofence so that Waymo can keep making money off of their collected data.
