A security researcher has shown it could cost little more than $60 to trick a self-driving car into seeing another car or person. Jonathan Petit’s research builds upon questions about the basic operating performance of autonomous vehicles after early models created by Google and Delphi came close to crashing during testing. An Arduino or Raspberri Pi computer would work for attacks of up to 100 meters in range of the laser ranging systems that help the cars see whats around them. Even vehicles operated by humans might prove equally susceptible to phony images interfering with tools such as driver assistance programs.”]
