This begs the question whether the safety monitors in the Robotaxis are also there to take blame for any of the vehicles' accidents.

I had never even thought of that! I had just assumed that Tesla would be responsible, but you know what they say about "assume!" Holy Cow! Now you've got me thinking there's another reason to not utilize a Robotaxi, buried in the terms and conditions that nobody reads could be a statement where you take full responsibility for everything the Robotaxi does. Yikes!
