I guess I'll do the obvious and ask for a source.

I saw the Tesla Vision keynote from Karpathy, if that's what you mean. Wouldn't call that a source for "official" tests.

The Tesla Vision only was tested by some state agency and has a higher score then the radar one. But only in terms of safety, I guess the software does other aspect as well.

There should be Tesla blog post about it or something.

> some state agency

Euro NCAP tested it. It doesn't get more official than that around here.
