The ‘few surprises’ thing is the issue. I don’t think we actually can calculate how many unforeseen scenarios these trucks can cause catastrophes because of specifically due to the fact that the are unforeseen.

I am thinking that until we get a much higher level of AI in cars, they will just not come as close to a human driver when it comes to situations it’s never encountered before. They don’t have the ability to be creative enough in those situations.

Maybe that will make up for trucker accidents that could have been avoided with non-human drivers, but I don’t think there’s any guarantee there.
