Hidden Obstacles For Google's Self-Driving Cars 289

Posted by Soulskill from the not-looking-forward-to-denial-of-driving-attacks dept.
Paul Fernhout writes: Lee Gomes at MIT's Technology Review wrote an article on the current limits of Google self-driving car technology: "Would you buy a self-driving car that couldn't drive itself in 99 percent of the country? Or that knew nearly nothing about parking, couldn't be taken out in snow or heavy rain, and would drive straight over a gaping pothole? If your answer is yes, then check out the Google Self-Driving Car, model year 2014. Google often leaves the impression that, as a Google executive once wrote, the cars can 'drive anywhere a car can legally drive.' However, that's true only if intricate preparations have been made beforehand, with the car's exact route, including driveways, extensively mapped. Data from multiple passes by a special sensor vehicle must later be pored over, meter by meter, by both computers and humans. It's vastly more effort than what's needed for Google Maps. ... Among other unsolved problems, Google has yet to drive in snow, and Urmson says safety concerns preclude testing during heavy rains. Nor has it tackled big, open parking lots or multilevel garages. ... Pedestrians are detected simply as moving, column-shaped blurs of pixels — meaning, Urmson agrees, that the car wouldn't be able to spot a police officer at the side of the road frantically waving for traffic to stop."
Paul continues, 'A deeper issue I wrote about in 2001 is whether such software and data will be FOSS or proprietary? As I wrote there: "We are about to see the emergence of companies licensing that publicly funded software and selling modified versions of such software as proprietary products. There will eventually be hundreds or thousands of paid automotive software engineers working on such software no matter how it is funded, because there will be great value in having such self-driving vehicles given the result of America's horrendous urban planning policies leaving the car as generally the most efficient means of transport in the suburb. The question is, will the results of the work be open for inspection and contribution by the public? Essentially, will those engineers and their employers be "owners" of the software, or will they instead be "stewards" of a larger free and open community development process?"'

        They don't have to determine exactly how much safer they are. They just have to determine that they are safer. Also, safety is just one of the benefits of SDCs. Other benefits include better road utilization, since they can drive much closer together. So highways won't need as many lanes. There will be economic benefits as fewer people need to own a car, since driverless taxis will be much cheaper, resulting in fewer cars but also fewer and smaller parking lots.

      Judging by how badly TFA was written.

      If a new stop light appeared overnight, for example, the car wouldn't know to obey it.

      Got it. So the cars cannot handle changes in traffic markers.

      Google's cars can detect and respond to stop signs that aren't on its map, a feature that was introduced to deal with temporary signs used at construction sites.

      So they cannot deal with new stop LIGHTS but they can deal with new stop SIGNS. WTF?

      But in a complex situation like at an unmapped four-way stop the car might fall back to slow, extra cautious driving to avoid making a mistake.

      And it would be "unmapped" for the first attempt. Right? Because the cars should be sending back data on road conditions and such to HQ. Right?

      Maps have so far been prepared for only a few thousand miles of roadway, but achieving Google's vision will require maintaining a constantly updating map of the nation's millions of miles of roads and driveways.

      And the car needs the map to drive, right?

      Google's cars have safely driven more than 700,000 miles.

      So they just drove over the same "few thousand miles of roadway" again and again and again and again? Until they got to 700,000 miles?

      The car's sensors can't tell if a road obstacle is a rock or a crumpled piece of paper, so the car will try to drive around either.

      As it should. Because you don't know if that piece of paper is covering a rock or a pothole or whatever.

      For example, John Leonard, an MIT expert on autonomous driving, says he wonders about scenarios that may be beyond the capabilities of current sensors, such as making a left turn into a high-speed stream of oncoming traffic.

      Isn't that one of the easier problems? The car waits until it detects a gap of X size where X is dependent upon the speed of oncoming vehicles and the distance it needs to cross PLUS a pre-set "safety margin".

      Put another way, if autonomous cars started off working on 0% of roads and you want them to eventually work on 100% of roads, well somewhere in between you have to pass through 1%, 5%, 10%, 25%, 50%, 75%, and 90%. It's rather disingenuous to criticize them for not getting all the way to 100% in one fell swoop. I'm shopping for a new car right now, and the new autonomous-like features like adaptive cruise control, lane change assist, and parking assist are really nice (haven't gotten to play with lane departure warning or assist yet). By themselves, no they don't make a 100% autonomous car. But each gets you a small fraction of the way there.

      It will be decades before these vehicles can handle real life situations. You will need AI that can improvise as well as a human. Good luck with that.

      I see that problem mostly being attacked from the opposite direction. With cars getting radar and proximity sensors, and being able to electronically communicate their intent with each other before actually moving, you reduce the need for the AI to improvise. If an autonomous car wants to pull in front of your car, the two car AIs will communicate it with each other and work out a plan to make it happen before changing lanes. No improvisation required. Sure you might get the stray deer hopping through traffic that requires a human to take control and improvise. But the vast majority of improvisation situations can be eliminated before they ever happen with better communication. That is after all the whole idea behind brake lights and turn signals - to allow you to communicate your intent to the drivers behind/beside you so they don't have to improvise in response to your sudden moves.

        Depends on how you define "special road". Google cars can only drive down roads that have been thoroughly scanned and analyzed by Google staff. Considering less than 1% of the roads in the US have been scanned and analyzed by Google I would call those "special roads".

    I'm going to map my drive to work, by driving it a few dozen times. Then the car can take over. I don't care if it's no good in parking garages or my own driveway. I'll spend 3 minutes driving from my house, let the car take over, let the car do the boring freeway driving, and it can alert me when I'm 3 minutes from work. Then I'll take over and get into the parking garage and park my car.

      Why not provide a mechanism so that when you drive over the road, data is sent to Google. Once enough people have driven the road, the data gets shared with all the vehicles, so it's as if they all have the latest map of the road.

      Also, there could be some mechanism designed for the DOTs, Police and construction workers, to "FLAG" a position and broadcast based on GPS coordinates as "X event now", OR "X even

              Also, it's up to the vehicle to distill that information, so they aren't necessarily uploading Gigabytes.

      And that is if you are the ONLY person with a robot car on that road. Which may be correct for the initial roll-out. But this is a great example of the "network effect". If 100 people in your state own robot cars then a LOT of your state will be continuously mapped / re-mapped / re-re-mapped / etc.

    Look this is a question of cost. Self driving car must be able to detect the end of road or a hole or whatever so if google did not already install a radar or similar to check the road status ahead, it would be incredibly dangerous. And a radar or similar detection device would be far better at detecting :
    1) pothole
    2) slowdown speedbump
    3) whatever the state of the road
    better than human say, at night. Or in the fog. Or distracted.

    Google isn't detecting potholes? Back in 1985, we had that on our DARPA Grand Challenge vehicle. The LIDAR on top of the vehicle was generating a ground profile. This was for off-road driving, where that's essential. I'd assumed Google was doing that; they have a Velodyne laser scanner that provides enough information.

    In traffic, sometimes you can't see a pothole because it's obscured by a vehicle ahead, but if the vehicle ahead doesn't change speed, direction, or attitude, it's probably safe to proceed over the ground it just covered. On high speed roads, you can't see distant potholes clearly because the angle is unfavorable, but if the road ahead looks like the near road, and the near road profiles OK with the LIDAR, the far road is probably good. That's what the Stanford team used to out-drive their LIDAR range. (We didn't do that and were limited to 17MPH).

    Fixed road components should be handleable. People, bicycles, and animals are tough.

    • Mercedes already has a pothole detector in one of it's high end models. Basically it's a camera tied into an active suspension that cushions the impact of driving over a pothole.

      I suppose it could be considered a solved problem.
