Nissan's Autonomous Car Now Road Legal In Japan 205

Daniel_Stuckey writes "The current test vehicle uses what Nissan calls its 'Advanced Driver Assist System,' which isn't fully autonomous, but rather can be thought of as a really advanced cruise control system. According to the company, the system can keep a car in its own lane, while automatically changing lanes to pass slower vehicles or prepare to exit a freeway, which it can also do automatically. Along with that, the car automatically slows for congestion, and — most impressively in my opinion — can automatically stop at red lights. In other words, the car isn't fully automatic in that you can't simply type in a destination and have it do all the work, but the bulk of driving load is taken care of. Curiously, Nissan's goal appears to be to take sloppy human drivers out of the equation to eliminate road fatalities."

        This actually worries me, the natural inclination will be for people to stop paying attention while driving. Then when the sutuation has surpassed the cars ability, nobody will be in control and an accident could happen. At that time, it will be assessed as the "robot's" fault and may set back adoption of what is likely to be a safer form of driving.

    Now it just remains to be seen if drivers will continue to pay attention to the road, or if it becomes so autonomous that people start slacking (more) behind the wheel. It really won't work to have a car that drives itself 90% of the time and then expects you go randomly jump in for the last 10%. Still, nice to see this tech getting closer to reality.

      That's what worries me. The transition to fully automatic cars needs to be essentially 100%, or at least 99% with a "pull over and stop moving" for the remaining 1%. Otherwise I would've be surprised if fatalities went *up* due to drivers taking a nap/getting drunk/reading a book and failing to notice when they need to take back over.

      • I dont think that is true at all.
        I think it will start the way most things do. Baby steps. Most likely there will be dedicated lanes to encourage people to adopt the tech. Like fast trax or something.
        No doubt there will be a charge by the state to actually use the lane though, thus reducing its appeal.

            Get ready to be annoyed for about 30 years, because "automated" commonly means "more automated than before," not "automated in every conceivable way."

            Your example about how this might cause a crash is incorrect, since the car doesn't just follow rules (such as red lights) in the hopes everybody else will also follow them perfectly. They do what you do - they also watch for and avoid other cars, pedestrians, and other obstacles (regardless of why the other car is doing whatever it's doing).

            Still I do worry about how they will accurately see stoplights and stop for the intersection even if no other cars are in view. There are bad lighting conditions where it's extremely difficult to do. (I guess as a backup it could know the GPS location of stoplights and stop if it doesn't see the light and confirm that it is green). But I am sure we will end up with some level of instrumentation on the road such as stoplights that emit at a frequency not obfuscated by sunlight, snow, etc, like visible light is.

I would assume that a panic stop would be a last-resort maneuver - if the logic got to an unhandled state or enough sensors were lost to warrant such a thing. I imagine that would be quite rare - probably less frequent than a tire blow out, for example.

      I have their system that's 1 step back from this: it can only steer gently with the brakes (using the brakes on one side or the other), but it will keep a safe distance form the car in front of you, even stopping as needed, keep you from drifting out of a lane if you're not paying attention, and, if you let it, brake for you in cases where it seems you're not paying attention. It's good enough that, even though you can't take your hands off

            Exactly. I put the small round mirrors on mine. I can tell at a glance if the lane is clear and if there is room for my entire car to move over without cutting anyone off. I originally got them for towing my boat so that I could see further back, but I find that they are invaluable as they completely eliminate my blind spot.

    • It sounds like people won't have to jump in randomly or unexpectedly, rather there are some types of roads that the system won't handle, requiring the driver to take over. It also sounds that if these systems sense a need to switch to manual control, warn the driver but get no response (hands on the wheel), they can at least bring the car to a controlled stop at the side of the road.
    • Now it just remains to be seen if drivers will continue to pay attention to the road, or if it becomes so autonomous that people start slacking (more) behind the wheel.

      That's a big problem with "driver assistance systems". With both lane-keeping and "adaptive cruise control" installed, the driver can take their hands off the wheel. Once that's possible, some drivers will stop paying attention to the road. That won't end well, because those two functions are only sufficient for good freeway conditions. They don't handle attempts by other drivers to change into your lane, for example.

    Is that drivers will stop paying attention and/or take their hands off the controls. Then when something bad happens that the automatic system can't handle they will be in a much worse position to deal with it than if they had been driving the car manually.

    The same is true to an extent of autopilots in planes but with a plane you usually have much more time to respond to problems than in a car. Still at least one plane has crashed because the pilots accidentally disabled the autopilot and failed to notice.

  • This is a good start but if cars "evolve" to be full automatic I hope they're going to include a bar in the final design. No more excuses for sobriety :)

  • As it helps reduce road fatigue, this seems a really good thing. However, it should require some sort of feedback that says when a driver is unresponsive in some way, the car pulls over and parks.

BLISS is ignorance.
