A car’s autopilot braking in the nick of time to avoid an “invisible” obstacle is basically a perfect viral video, surely that would be a top post here and on Facebook and Reddit if it existed
Absolutely right, this should be considered the bare minimum of driver assist, let alone "self driving".
That would be real magic. Magic is numerous cases where Autopilot does end up avoiding accidents in otherwise mundane situations that most people don't even think about, but over time does make a big dent in the number of fatalities.
