Can a swollen savannah monkey brain drive a car safely on public roads, using nothing but its attached eyes and ears? Yes (most of the time). Can AI do it? Not yet...
Supposedly the development versions we the general public can’t get yet are getting pretty good and would meet your “most of the time” bar on public roads.
But we don’t really know how good AI is at any given moment, because those that are leading in any AI area sometimes have reasons for not telling yet. Or because we don’t believe them when they do tell us.
