NHTSA Suggestion Would Cripple In-Car GPS Displays 516

bricko writes "The recently issued National Highway Transportation Safety Agency guidelines for automakers to minimize distraction for in-vehicle electronics included a proposal to freeze maps on navigation systems. No more scrolling maps...just static pictures. 'Every current installed navigation system uses the car as a fixed point, and shows the map moving around it. NHTSA wants that changed so as to keep the map fixed. Even showing the position of the car moving on the map could be considered a dynamic image. The recommendation seems to suggest that the position of the car could only be updated every couple of seconds. Likewise, the map could be refreshed once the car has left the currently displayed area. This recommendation would essentially make navigation unusable. The system could still give an auditory warning for the next turn, but without being able to glance down at the map and see how close the next street is would likely lead to a lot of missed turns and resultant frustration.'"

    I swear, government must be run by the lowest common denominator.

    Your brain will easily tune out a smoothly scrolling picture that has minute changes one frame to the next. A change in the visual environment that is small will not trigger a threat assessment by the brain.

    However, if the image is still, and then suddenly changes, that is a far more significant change in the visualized environment, and the brain will tune to it to see if that change represents a threat.

    *shrugs* If I need GPS, I use my cell phone. It has current maps, and doesn't require me to buy a $200 update every few months so I'm up to date.

    I also stuff it in the cup holder and just listen to the auditory commands, if I'm using it for navigation. The screen *is* a distraction. If I want to study the route, I'll do it when the car isn't moving.

    Actually, to that end, I'm a bit surprised that the NHTSA isn't suggesting that the in-dash navigation systems should blank the screen while the car is moving. That would make things significantly safer, I think.. they could even make it so that if it's pulled out and facing the passenger seat instead of the driver, the screen unblanks and updates, so that a passenger can give directions.

    For those of you bleating about how this idea will make GPS "unusable", I have one question:

    Have you ever used a paper map?

    Remember the "bad old days" of folding out the map at the side of the road, looking at it, and planning the next leg of your trip?

    That's right: figuring out where and when you have to turn BEFORE you reach the turn. Actually KNOWING where you're going instead of letting a machine do the "thinking".

    This change would not cause the world to come to a sudden end, but it might well force people to think and plan for themselves again. And if that means some brain-dead loser suddenly can't get where they're going, I say "good riddance -- you were a road hazard anyhow, careening around the streets with no idea where you are going."

    Growing up, I remember the bad old days where my dad was trying read a map at the same time as driving, when I was to young to act as navigator. Or a couple of near hits on his part while navigating a foreign city looking for a specific street sign and not really watching the road.

    He now uses GPS and is probably safer than most of my generation, because he doesn't know texting and isn't addicted to a smart phone, but that's another story.

    1. All this will do is encourage people NOT to waste $2,500 on in car GPS units and use their cell phones handheld or mounted to their dashboards.

    2. It clearly shows the NHTSA hasn't done any real research on this issue. If they had, they would have come out with a much different solution. My own independent research has made it clear that GPS units screen movement are not the issue but the location of the unit. (off to the right, centered in console)

    Safety would be greatly improved by relocating the GPS console to the driver's side directly in line of sight, and with a night heads-up display even better. Why is this? Because having it in the center of the console forces drivers to look away from the road, and offers ZERO reduction in distraction. However, placement in front of the driver's line of sight does something interesting. Even when the driver is distracted by looking at the screen, the road remains in the driver's line of sight, and the driver's peripheral vision remains on the road.

    Peripheral vision is attuned to movement. A driver is able to still be alerted to an incoming car or obstacle even while focusing on the GPS screen when it is position properly.

    Indeed. I refuse to use a GPS where I can't have a map with north up, but instead have to rely on the constantly shifting view made for people who can't read maps nor think further ahead than the next turn, but can only relate to the direction the car is going in right now.
    What's really sad is how such a large part of the population lacks skills that were common. Like estimating distances, giving correct change without a calculator, making a meal from scratch or reading a map. People don't use technologies to make things they know how to do easier, they use them so they won't have to learn something in the first place.

    At my best estimate, this Great Age Of Ignorance became mainstream in the late 80s, early 90s, and has continued since. There used to be a saying that someone was so dumb that they couldn't find their ass without a map, but these days, the average Joe or Jane would look dumbly at the map.

    If you can't read a map but rely on POV views, I don't want you on the roads without special dispensation and training. You have no spatial awareness, and are a danger to others.

    Unfortunately most brains aren't good at multitasking. Well, speaking for myself: Mine isn't. The good thing about a navigation system is that I can pay attention to the road and spend very little time worrying about where to go. I need an occasional glance at the screen to resolve an issue (Navigon isn't very good; TomTom is pretty good), other than that it isn't really a distraction. I've to spend less time watching road signs for directions as the information comes in audio form to me. The info also also always repeated, so I can ignore it if it doesn't suit me because of a complicated traffic situation that deserves my immediate attention.

    Remember the "bad old days" of $SOME_CRAPPY_THING_THAT_OLD_PEOPLE_THINKS_MAKE_THEM_HARDCORE ?

    Fixed that. Some things are just better than other things. Nav systems are one such thing. Further, the best nav systems display the upcoming turn from either the driver's POV or a close-in top-down with forward displayed up. This is helpful when a glance can give indication of where exactly the turn is. This is invaluable particularly with irregular or dense intersetions, where a verbal "turn right in a quarter mile" could yield 20 options.

    I hate driver distraction as much as the next guy, but when one glance down for a quarter second can actually make the driver safer, we'll cope.

    Look at the dearth of numerical LCD gauges in cars. Why is that? We used analogue meters back in the day because, well, that's all we had. However in a modern car, that instrument cluster is part or all digital on the back end. It has to convert the digital signals it gets to the analogue gauges. So why not go for digital LED numbers? Cheaper to produce, and more accurate. You'd know your speed down to the MPH (presuming the unit that reads it is that accurate). In fact there were some cars with them at one point, but they seem to have gone away.

    Well the reason is it is distracting. If you put a big LCD speed readout there it's abrupt changes distract the driver more than the smooth movement of a needle. Quick changes catch the eye, smooth motion not as much.

    Same would hold true for something like this. A smooth updating map that scrolls along with car movement isn't very noticeable. Something suddenly changing draws the attention.

    Very good point. It's an odd example, but kind of applies. In the game Angband (a roguelike), there is an option to keep the map centred on the player. Normally I don't use this, because it slows things down on slower hardware, and the game has my full attention. If however I get teleported somewhere, I do fine myself needing to spend time trying to locate myself, as it's not immediately obvious. It seems silly to place drivers in the situation where they must spend time scanning the map for their car.

    Ideally though maybe it's best that devices are required to blank the map when the car is traveling above a certain speed, relying only on audio prompts. Driving along, slavishly following the visual instructions on screen seems about as safe as the practice of trying to read a conventional map while driving. Look at people walking down the road, looking at their mobile phones. Does anyone not regularly have to get out of the way of these people? this shit is too distracting. The last couple of times I've had near misses as a pedestrian have oddly enough been while people were talking on phones, except of course for fucking cyclists who think that stop signals don't apply to them, and will happily weave through a line of people crossing.

    I always find it amazing that electronic gadgets are a "distraction" yet non-electronic ones are not. You don't see legislation to outlaw paper maps, coffee cups, makeup, food, etc from vehicles. Yet we see state after state as well as the feds weighing in on the rush to make electronic devices illegal or unusable while driving.

    Look, it is all about the revenue these laws and regulations generate from the tickets they issue. It has very little to do with safety. If it had something to do with safety they would stiffen the law that covers distracted driving (reckless driving) more and leave the reason for the reckless driving out of it.

    In my home state of West Virginia this year they just passed a law making use of a cell phone illegal while driving. That isn't the part that shows it is about revenue. The revenue generator is it was made a primary offense with a stiff fine attached to it. Meanwhile that law does very little for any other form of distracted driving.

    GPS systems are a huge distraction. Do you really need a GPS for day-to-day driving? For most people, how often do you really drive somewhere you don't know? No more than a few times a year. And do you really need a GPS in a city you don't know? No. READ THE ROAD SIGNS! CHECK A MAP BEFORE YOU LEAVE! Folks that drive with GPS seem like some of the worst drivers on the road. Why? They are watching the screen and not the road signs. They are missing the obvious visual clues to where they are going.

    GPS laws might not get much traction. Most places it's illegal to drive while on the cell phone but people still do it. Somehow, you put that iPhone in a dash mount and people somehow thing it is now a legal "hands free" device. People need some common sense.

    For that reason, paper maps are *far* more dangerous to use while driving. No use glancing at them, you need to look at them for a bit to orientate yourself and make sense of them. Yes, you could study the map before you leave, but most people are not really able to memorize the complete route, and it certainly isn't easy to re-route if you miss your turn.

    Our former head of traffic police (in the Netherlands), who is notoriously averse of gadgetry in cars, quoted several studies that navigation systems are by far the safest option for navigating an area that you're not familiar with, winning over memorizing maps, having paper maps in the car, stopping to ask directions, or just winging it. The one thing that is safer is having a co-pilot with either a paper map or a GPS.

    It's even worse than that. When the in car navi stops working the way people are accustomed to they will switch to phone based navigation which will require much more attention and cause many more problems. Rather than constantly trying to put genies back in their bottles government out to be researching ways to make them safer while still being useful. Figure out a way to have them be voice activated and respond to natural language queries so the screens become less important to the experience.

    If you want to change people's behavior give them something that is a qualitatively better experience rather than just trying to restrict what already exists. This will only drive them to (pun intended) to work around the system with unforeseen and in this case dangerous consequences.

    I would argue that the reason we have analogue displays is that they are easier to comprehend. In my car I can glance at the speed and tach and comprehend the meaning with no reading, or minimal reading. The meaning is purely positional.

    There is technical issue as well. Can a car calculate the speed to miles per hour and if so, is it meaningful? I would argue that a car cannot reliable calculate, on a second by second basis, the speed to such an accuracy and therefore such displays are there purely for entertainment purposes. I would argue that we are seeing an increasing number fo displays that are for entertainment purposes only. For instance, I rented an Altima that displays frequent updates to current fuel usages, which went from 60 mph on the down slope to 10mph on the step positive grades. This was not useful. My car gives me a trip average which potentially allows me to adjust my driving when the average is to low. The gauge on the Altima is entertainment.

    And I think this is what the discussion is about. What part of mapping is useful and what part is visual entertainment, which many agree is not appropriate for the driver. I don't have one of these devices in my car, but from what I have seen driving with my friends is that the device tells you what you need to do, and all the driver needs to do is listen. There is no reason to constantly check the display. Now, I don't want those instructions, so I when I am going to a new place I figure our where I am going beforehand. It seems more dangerous to me to have to look at a map while on the go, and maybe have to make extreme changes in lanes or speed, or fast turns, rather than having the navigation planned in advance. Of course, with the computer telling you the navigation, that is fine. But checking a map to determine the navigation, that just sounds dangerous. You may as well be watching a movie.

    There are so many streets out in the area I''m at that either don't have signs or have small, hard-to-find signs (imagine trying to find a sign on a random corner of an intersection of a 4-lane-plus-turn-lanes road and a 2-lane side road, with trees and poor lighting). Often by the time I've found the sign, assuming I even find it at all while making sure I don't hit something, I've gone right through the intersection I was supposed to turn at. I've seen a lot of accidents and close calls caused by people slowing to a crawl coming up on an intersection, presumably trying to find the sign to see what street they've reached, sometimes swerving into the turn lane at the last second. I don't want to be one of those.

    For some reason, the DOT out here doesn't seem to have heard of the concept of putting the signs up on the traffic light cross-poles or even putting up signs on multiple corners of a large intersection.

    I love my GPS just for that.

    It's just an added bonus that I don't have to pull over and pick up the tattered old map to remind myself which tree-named street I want again, and is it the 3rd or 4th turn after the last major intersection that I haven't reached yet, and then is it left-right-right-left or left-right-left-left once I get into the subdivision. It's not because I can't use a map of because I'm lazy, but the GPS is so much easier and a time-saver, that I am able to concentrate more on the driving and not on where I'm trying to go, that I feel it's much safer to use the GPS than to not use it.

    It should be illegal for any screen of any type to be visible to the driver of the vehicle.

    What's the difference between a screen displaying operational data (like navigation) or any of the various gauges that you use to operate the vehicle?

    For instance, I find myself very distracted by constantly looking down to my speedometer when going through some of the areas around my home where the local police will nail you for 35 in a 25. I'm so (necessarily) fixated on the speedometer, I can't actually *drive*.

    GPS devices are FAR safer than the alternatives. I don't know if you remember what the world was like pre-GPS, but it wasn't at all uncommon to have a map unfolded on a seat next to you that you consult from time to time when navigating through unfamiliar territory. A quick glance at a GPS which shows me a 3D representation of the route I need to take hands-down beats several seconds of scanning a map to figure out where I am and where I need to be.

    Or people will just move back to using portable devices instead of ones that are part of the car.

    I pipe the audio output of my smartphone through my car's speakers. I also use it to listen to music on occasion: the music is automatically paused while the GPS is talking so there is no confusion. As it happens, I normally use Google Nav, and the voice works well enough that I rarely need the display. So well, in fact, that I usually just leave the phone in my pocket. If you do need to constantly look at the screen, it probably means your navigation system is poorly designed, or perhaps you are just a very insecure person. My girlfriend has dedicated GPS from Magellan, and it's turn-by-turn likewise works very well (somewhat better than Google's system in many cases.)

    I agree with some other posters: get the units with low-quality software off the market. The government would do better mandating improved functionality rather than imposing arbitrary (and fundamentally dangerous) restrictions, restrictions which serve only to demonstrate how out-of-touch that particular bureaucracy is with this technology.

    So, I think the NHTSA is a barking up the wrong tree. Mandate GPS use training in driver education and be done with it. Penalizing the bulk of the population that has no problem using GPS successfully for the misdeeds of the few is just bad lawmaking. It will, however, be profitable for the locales that implement such regulation, so I have no doubt that many will.

The study of non-linear physics is like the study of non-elephant biology.
