If you're near Station Square on the South Side or the National Aviary on the North Side, keep an eye out for Argo AI's self-driving cars. The Incline readers and staff have spotted the autonomous Ford Fusions -- often full of people -- more and more in the areas just south and north of Downtown. But the testing locations and the riders are signs of what's to come in 2018 for the self-driving startup. "You're seeing the first steps in expanded testing efforts," said Alan Hall, spokesman with Ford, which invested $1 billion in Argo AI a year ago. In September, The Incline launched a map to track where self-driving cars are testing in the Pittsburgh area since the multiple companies doing the testing won't provide the specifics.
