No mention of a driver in the sedan. The article reads as though the vehicle was acting on its own. 

These statements from the police don't help:
A vehicle struck a pedestrian Tuesday morning in Midtown Anchorage, then left the scene, police said.
"A four-door tan sedan hit a pedestrian headed east on Benson," police spokeswoman Anita Shell said.
"We had gotten a couple of different reports from people," Castro said. "We have not located the suspect vehicle in this case."

Anyone remember Maximum Overdrive? We may be worse off than we thought if there are mad vehicles out to injure or kill.
