"Just how much was she being paid?"
Enough for her to accept the job.
"What degree of training did she have on the capabilities (or otherwise) of the "automated driving" system?"
That's a good question, While she took the job we don't know what training was involved or what expectations were set, but watching a TV show on your phone while on the clock is probably not in the 'acceptable' column. The title is "Safety Driver," not "Safety Passenger."
If you walk into McDonalds and the person there to take your order is playing Angry Birds and is very slow to respond to you being there, how do you react? In a retail store, you come to the cashier and they are engrossed in texting and don't notice you, what goes through your mind?
I doubt you're thinking "They're doing a great job."
