Google last week announced that it has developed technology for its self-driving vehicles that would be able to detect people in costumes -- presumably children dressed for Halloween.
The company is teaching its cars to drive more cautiously around children and thus be ready to adapt to sudden and even erratic movement, it said.
Google's engineers are striving to help the cars react, especially as children's behavior can be unpredictable. The vehicles are designed to scan for those in costumes or other garb that might make them not immediately recognizable as a person.
