How our self-driving cars see the world. The predicted future path and multiple possible interactions of every person, car, and cyclist are calculated 10 times per second.
Traffic lights out at 6-way intersection. All driving completed autonomously.
Passing a box truck in Chinatown. All driving completed autonomously.
Humans controlling traffic near construction. All driving completed autonomously.
Cyclist cutting off a car at night. The driver took over, but post-analysis shows our vehicle was already braking and would have stopped in time to avoid a collision.
