Emergencies are noted exceptions to Level 5, so the "A first responder insists on driving the car" case is still level 5.

Waymo has level 4 taxis in two US cities and is running tests elsewhere too. The usual reaction from the "This can't be done because somehow driving a motor vehicle is a uniquely human ability" people in those cities seems to be head-in-the-sand refusal to believe. The good news is that if they choose to believe a Waymo doesn't exist and step in front of it, it'll probably brake politely to a halt like they're any other asshole.

Level 5 mostly requires more range. I don't think this bet is a sure thing, but it's certainly possible that Waymo's reason you can't go from say New York City to Birmingham Alabama in 2030 is something that sounds like a taxi company reason rather than an "Our AI can't do that" reason.
