At the current state of the art for self-driving, this simply is not true. Humans are much better, on average. That's why the vast majority of cars are still driven by humans.
The technology will keep improving, and at some point one would expect that it will be more reliable than humans. But it's significantly less reliable now.
I think Tesla is somewhat reckless with self driving, but we all need to agree humans aren't much better and don't generate any controversy.
