Aurora, the buzzy self-driving car startup, has become the first company officially authorized by the Pennsylvania Department of Transportation to test its vehicles on public roads.

Aurora has been testing its autonomous vehicles on public streets in Pittsburgh since late 2017. And other companies such as Argo AI also test autonomous vehicles there. So receiving an “authorized tester” designation might seem a bit backwards.
