“There’s still too many questions and the potentials are there, so that’s the beauty,” said Kopko, PennDOT manager of traveler information and advanced vehicle technology. Fully autonomous vehicles need to cover two domains: highway driving and urban driving.  “Technologically, we’re pretty much there in terms of highway driving,” said John Dolan, principal systems scientist at CMU’s Robotics Institute. The demands of urban driving are “problematic,” he continued. “Nobody’s really claiming they’ve solved it.”
