Just a quick Google search and the first results give me this info:
>Nearly 1.3 million people die in road crashes each year, on average 3,287 deaths a day. An additional 20-50 million are injured or disabled. More than half of all road traffic deaths occur among young adults ages 15-44.

Of course unmanned driving tests will happen at a very, very small fraction of the amount compared with manned drivers we have to pull stats from but I don't think it will take long, if the unmanned tests persist enough to conjure up the required amount of data needed to make a legitimate comparison to prove that unmanned driving will be markedly safer.
The only person who died in a road fatality in phoenix that day was killed by a self driving car.
Uber, with their recklessness, is inflaming them a lot.
