　　Ever wonder how those Google cars don't hit you during your morning commute? The company revealed its sensor technology under the hood in a  Youtube video.

　　The video shows how the sensors recognize other vehicles, cyclists and pedestrians around it to keep a safe distance from them.

　　"It can detect hundreds of distinct objects simultaneously — pedestrians, buses, a stop sign held up by a crossing guard, or a cyclist making gestures that indicate a possible turn," The video says.

　　According to the blog post this morning, Google's logged a total of 700,000 autonomous miles on the road.
