Driverless cars are set to become smoother and more intuitive after scientists developed technology to make them behave like humans. One of the stumbling blocks with autonomous cars has been their inability to interpret visual cues from pedestrians, making them overly cautious. So when a person begins to cross the street but changes their mind a driverless car might just just stop and wait. But engineers at Perceptive Automata have developed artificial intelligence software which enables driverless vehicles to understand the state-of-mind of people, including pedestrians, cyclists and other motorists.
