The review will cover everything from the self-driving system itself to training for the operators. Uber isn't saying more at the moment, but promised additional info soon.

There's a certain amount of public relations maneuvering involved: Uber wants to show that the crash was an isolated incident, and hiring a national safety leader will do that. At the same time, Hart's advice and the review demonstrate that Uber isn't taking the incident lightly. It knows it has to prevent another incident if self-driving cars are going to take off, even if that means taking drastic steps.
