NHTSA Suggestion Would Cripple In-Car GPS Displays
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.'"
People will just realize they are about to go the wrong way and change lanes even later than they already do.
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.
Drivers should focus on the street and the traffic and not being distracted by some ads.
"This recommendation would essentially make navigation unusable."
Paper maps don't scroll OR indicate where you are. They've been providing perfectly usable navigation services for thousands of years.
Oh, you mean "automated I'm too lazy to figure out where I'm going before I start the trip because I can't be bothered to learn which way is north" navigation?
I don't see anything outlawing voice systems. Do you?
*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."
I do not fail; I succeed at finding out what does not work.
Not only that, but the car's velocity would no longer be conveyed with a static display. It's why digital numeric-readout speedometers were a failure in 1980's Fords -- they didn't convey acceleration.
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.
D@|\/|N Government....
While we're at it, why not get rid of all those other dynamic displays: gas gauge, speedometer, rear-view mirror ...
Well that's moronic. What if you're the passenger. *sheesh*
While they are at it, perhaps the tachometer and speedometer should be frozen, since they could be distracting. Make the turn signal indicators solid... that blinking can be distracting. Better make sure there is no sweep/seconds hand on any clock.
And passengers- especially children, those should be frozen too. They are MAJOR moving distractions.
Oh- they should repaint all the lines on the roads to not have dashes, since those appear to be moving. Mirrors....
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.
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.
The ones who thought it was a good idea were the bean counters who figured they could save themselves a few bucks by not having two different dashboards for left or right drive cars. But you know, "safety is our first priority... right after money." (Like the airlines!)
Generally speaking, I agree with you. On the other hand, I know some people (my wife) who can't navigate anywhere and are constantly turned around. The reality is some people have a good sense of direction and can memorize a map with ease, and some people can't.
I'd rather have my wife using a GPS then call me frustrated while trying to describe where she is while actually having no idea and just becoming more and more angry.
I don't have time to make a sig
I am wasteing my previous mod points but oh well I do not have a in car navagation system or gps or even smart phone with internet, but you say that people do not need gps nav because most people do not go all that many places that they do not the way to all that often. That may be true for you but if for people like me who go trying out new hiking and camping and fishing places way out in the middle of nowhere on back roads a nav system would be a God send. I hate trying to read a map while driving and no reading it before hand is not always enough. If I am driving clear across Washington state to go fishing with freinds just glancing at a map before leaving is not enough. Just because you do not have a use for it does not mean others do not have a use for it.
---Saying gnome 3 is better than windows 8 not so much a compliment as it is damning with light praise.
If you want to eliminate distractions, make handheld cellphones inoperable while moving.
As a bus and train passenger, I thank you for that suggestion. Not only will I be unable to use a cellphone even if I'm not endangering anyone, as I'll have to waste all my battery to keep the GPS always-on, in order to ensure that restriction.
