> Would also be interested to know if there's a way police could work with Tesla or other autopilot carmakers to broadcast special codes like don't-hit-us-here-is-our location, or just send a signal blocking autopilot, or whatever. They already send texts and radio alerts, and there are already local AM alert stations in the US anyway. I don't think this will be a good solution, since inherently these incidents happen when there's an "exception". If every stationary emergency vehicle had to send a notification each time the lights were activated, this would maybe work, until you're in an area without coverage. To me, we need to raise the bar for what's acceptable - this vehicle would presumably also have ploughed into an injured motorist's car before the police had arrived... The root problem isn't the lack of notice of the stopped emergency vehicle, rather it's the apparent inability to avoid a stationary vehicle on the roadway, which should be the very first (and simplest) thing to detect, since the self driving vehicle is closing in on it and can see its relative position isn't moving. If it can't do that, IMO it shouldn't be on a public road, as it isn't capable of basic speed management in traffic without being able to gauge closing speed against a vehicle ahead.
