Waymo Says Autonomous Pacifica Would Have Avoided Crash Caused By Human Error

Waymo has revealed to the DMV that, on October 19, one of its autonomous vehicle prototypes had an accident with a motorcylist.

The San Francisco Chronicle reports that the accident happened near Waymo’s headquarters in Mountain View, California and that the human backup driver was in control of the vehicle at the time of the collision.

In its accident report filed with the DMV, Waymo says that its Chrysler Pacifica prototype was driving at 21 mph (33 km/h) in the middle of three lanes when a car in the left lane began to merge into the middle lane. Eager to avoid an accident, the human operator quickly took control of the car, disabling the self-driving systems, and started to move into the right-hand lane.

However, there was a motorcycle traveling at 28 mph (45 km/h) in the right-hand lane and it hit the rear bumper of the Waymo prototype.

Waymo says the accident could have been avoided if the vehicle was left to its own devices.

In software simulations run by the technology company after the accident, Waymo discovered that the vehicle would have slowed down to avoid the car merging from the left, avoiding a collision.

In a blog post discussing the incident, Waymo chief executive John Krafcik said the car had a 360-degree view of its environment the entire time.

“Our self-driving system was simultaneously tracking the position, direction and speed of every object around it,” he wrote. “Crucially, our technology correctly anticipated and predicted the future behavior of both the merging vehicle and the motorcyclist.”

    Now imagine if all cars had such capability. Thousands of crashes have already been avoided by simple AEB. So many lives will be saved one this technology becomes widespread.

    Here’s a certainty- this accident would not have happened if the autonomous car was on a private test track, and not using public roads and citizens​ as guinea pigs.
    I am tremendously pleased to see UBER’s autonomous ‘testing’/Hulu watching has remained off the public roads in Pittsburgh. We absolutely do not miss the slow-moving XC90s stopping wherever they please, impeding traffic, refusing to make right turns on red.
