I don't know anything about the industry, or definitions, or terms used. I'm just "a person in the street in a hurry". "Unsupervised" sounds like you can take a nap in the back while the car takes you somewhere to me. What's an appropriate safety standard the self-driving car must meet to make that safe enough? I'd say that the self-driving needs to be [at least] as reliable as a human driver. If someone said that the average human driver has some kind of failure (loss of attention causing accident, feels unwell and needs to pull over, etc) once every 122,000 miles, that sounds about right to me.
