Self-driving cars are actually only legal in a few countries. And those countries have tests.

It's only the United States that just lets anyone do what everyone earth it is that they want, even if it's insanely dangerous.

Everywhere else any car company that's espousing self-driving tech would actually have to prove that it is safe, and only a few companies have managed to do this and even then the cars are limited to predefined areas where they are sure they're not going to come across difficult situations.
