If the robocar were to warn once, and then steadily slow, all drivers would learn to take over when warned.

I don't disagree - like I say, none of my comment was intended to let Tesla off the hook in any way.

My point was simply that the drivers who use semi-automatic cars and choose to ignore warnings to retake control need to be responsible for their actions as well.
