NEXT TIME YOU’RE driving down the road or walking down the street, pause to consider how you read your surroundings. How you pay extra attention to the kid kicking a soccer ball around her front lawn and the slightly wobbly, nervous looking cyclist. How you de-prioritize the woman striding toward the street, knowing she’s heading for the group of friends waving to her from the sidewalk.
You make these calls by drawing on a lifetime of social and cultural experience so ingrained you hardly need to think about it. But imagine you’re an autonomous car trying to do the same thing, without that accumulated knowledge or the shared humanity that lets you read others’ nuanced behavioral cues. Treating every pedestrian, cyclist, and vehicle as an obstacle to be avoided will keep you from hitting anything.
