Every year, the Navigant Research Autonomous Leaderboard report ranks the various players in the autonomous mobility space and every year it prompts much wailing and gnashing of teeth from fans of companies who trail in the rankings. To help explain the factors that go into these rankings and the methodologies used measure them, we are joined by the report's author Sam Abuelsamid. A widely-respected analyst covering autos and autonomy, Sam was last on The Autonocast back in January of 2018 when he explained that year's Leaderboard in episode #47.
