From the article:

>> Uber first made its interest in self-driving cars public when it hired about 40 researchers and scientists from the National Robotics Engineering Center at Carnegie Mellon University in 2015.

It doesn't sound like "they don't really have the expertise" (per your comment).

Perhaps autonomous driving is even harder than press releases from other, more cautious companies, have led us to believe?
