Inside the secret site where cars learn to drive

There was a man in a straw hat who crossed the street over and over again to earn a salary here.
Sometimes, he looks down at his mobile phone and often hovers outside the crosswalk. He also ignores traffic signals.
What he did not do was pay attention to the car passing through the intersection.
If he did, he would notice that they did not have a driver.
This carefully shrouded 91-
The acre reserve in California\'s Central Valley is a test ground developed by self-driving cars Waymo
Before the split last year, the car company was part of Google.
Waymo separated the door of the high chain. link fence -

Last week, they welcomed a car reporter because they knew that the challenge they faced was not just to develop \"perfect\" driverless cars.
\"There will be a certain degree of discomfort in sitting in a completely driverless car,\" said Waymo chief executive John clafchick . \".
\"We have read most of it [surveys]
Most of the time, they say about half the drivers feel uncomfortable with the idea.
When we see this, we say, \'That\'s cool-
About half of the users are already happy with the idea of self-driving.
We actually think this is a reasonable starting point.
\"The place to start may be more frustrating than this.
A AAA survey this year found
For several quarters, people said they did not dare to take driverless cars, and more than half of drivers did not even want to share roads with driverless cars.
People at Waymo and many other companies are eager to get automated cars on the road, noting that once people experience cars, they usually turn to technology.
Waymo says driverless cars have started driving.
In 5 million miles in 22 test cities, 2 were accumulated.
In last year\'s simulation alone, 5 billion miles were challenged by about 20,000.
If they are in situations that they may encounter on highways and city streets.
The company sent a blind man alone in a car in Austin, but mostif tests (
Called the \"disaster of love\" experiment)
It was at the former air force base and an early facility at Google\'s headquarters 120 miles from Mountain View, California.
Since the Austin test in 2016, Waymo vehicles have moved from a gumdrop-
It\'s like looking at a Chrysler Pacific minivan that looks normal, except for a dome that\'s as big as the old one on the roof --

This is a level 4 self-driving car.
For minors who may be afraid of the future of driverless, this means that if there is any problem, the car has the ability to park safely without driver intervention. )
The detection system layer collects more data

More than human drivers can absorb.
Lidar detectors use pulse lasers to measure the distance between objects, mounted on front and rear bumpers, right in front of the side

This complements the radar sensors in the four corners and top of the car.
They picked up the straw hat together, several cyclists passing by, a row of traffic cones, and changed the traffic lights.
The van also successfully negotiated a roundabout and dealt with three what-

Cars can also hear the sound. The computer -
And the backup computer that monitors it and takes over it in case of any problems-
There is Waymo\'s software that says \"can model, predict, and understand the intent of each object on the road.
\"Pedestrians, for example, go slower than cyclists, motorcyclists, or cars, but they can change direction faster.
Then the \"planner\" of the computer \".
\"If your software believes that an adjacent lane in front is closed due to construction and predicts that cyclists on the lane will move, according to the Waymo manual distributed to reporters, our planners can make a decision in advance to slow down or make room for cyclists. \".

\"We will not give you a specific date.
We will do it when we are sure we are ready.
\"The details, they say, are fairly small, such as helping an empty car better understand where it should be carrying passengers, or where the car chooses to get off --

Unlike the big-
Google has decided to jump directly to completely driverless cars, and companies that sell cars every year plan to gradually launch products such as lane sensors and radar.
The reason for this decision has grown to legendary levels in the industry, with krafitch showing the worst slides: Google\'s own employees make up and text while driving
Semi-autonomous test car
The last slide shows a driver sleeping at 55 miles an hour.
\"We closed this aspect of the project a few days after seeing this,\" he said . \".
Waymo and its competitors will also have to convince one and a half.
The public is skeptical about the safety of completely different modes of transport.
People in the industry like to cite a specific number, and krafitch does the same: 94% of crashes are caused by human error.
This means that 6% is caused by other reasons, and driverless car manufacturers know that when one of their cars --
Even the fault of another car.
A crash occurred.
Convincing passengers that everything went well was one of the reasons Waymo had a pair of video screen monitors installed.
In the case of pacsifika, they were embedded [Otherwise empty]front seats.
Ryan Powell, head of the Waymo user experience design team, said: \"We are obsessed with presenting the right information at the right time . \".
360-amount of data collected
The degree sensors and cameras are huge, so Powell\'s team is selective: other cars are blue blocks, pedestrians are white circles, bicycles are light blue circles, traffic cones are yellow.
When someone walks, rides, or approaches a crosswalk, the crosswalk is brighter and darker if they are empty. Traffic lights?
Of course it\'s red, yellow or green.
\"On the one hand, we are very excited to show how much our cars can see,\" Powell said . \".
\"At the same time, we don\'t want users to be overwhelmed.
\"While some sidewalks come from the Air Force Base, which was closed in 1995, Waymo has created a maze of roads, traffic signals, curb stones, lanes, potholes, test the sink of the car and the working railway crossing.
\"Structured testing allows us to model and present challenging scenarios that exist in the real world,\" said Stephanie vilgas, system engineer in charge of the structured testing team.
They put three on media day.
Among them, a Honda convertible suddenly cut off a Pacific car as it passed a crossroads, which brakes to avoid it.
On the other lane, a car covered by two parked cars suddenly retreated from the lane.
Passifika is again at a standstill.
The third one is fake.
During the day scene, there was a sofa on the street, the box rolled in the driveway, just as the other car approached in the opposite direction.
The pacsifika are more clear than turning to the car.
It didn\'t brake until the coast cleared.
After about 20,000 such tests since 2012, Villegas seems happy to have an audience to show. \"It\'s so fun! \" she said.
\"I\'m glad you\'re all here.
