Waymo seeks Arizona volunteers for rides in self-driving cars

"Passengers in the Waymo and Uber vehicles in Arizona are probably safer than passengers in traditional vehicles, said Bryant Walker Smith, an assistant professor of law at University of South Carolina who has studied the automated vehicle programs.

"I’m concerned about automated vehicles, but I’m actually terrified about today’s drivers in today's vehicles," he said. "If you think about the amount of research and development in these vehicles versus a traditional driver ... someone who is texting, someone who is drunk, someone who is in a vehicle that is un-maintained.""
