"The poors" can still use their non-integrated GPS, just in a safe (set your destination before you drive, pull over to adjust) manner. That's what everyone should be doing anyway.
Someone else posted a response to a similar point, higher up in this thread.
"They aren’t paying attention and when the light turns green they may either hit a pedestrian as they hurry to move , or not notice the green and be rear ended by a driver who expects them to begin moving."
People who don't drive new enough cars to have integrated GPS buy a suction cup mount for their phone. It's not 2012 anymore, everyone has smartphones, nobody but truckers uses standalone GPS.
I know this crowd is too high class to know what it's like but something like using your phone for GPS can be the difference between leaving a fishing stop with a warning or a ticket depending on what kinds of citations the department is trying to prioritize.
Here in south australia, if you're on your P1s you cannot use mobile phones in any way while driving, including handsfree and mounted GPS function. I got a Garmin (as a birthday present) which I still use even though I can use my phone now, since it's actually very nice (especially traffic/red light camera warnings, school zone and speed limit change notifications, live traffic, etc.).
I'd be heartily in favor of phones being banned from being used as GPS/navigation aids, since it seems most people don't have the self control not to interact with their phones while driving - it would remove it as a distraction and hopefully prevent "opportunistic" phone use.
What I'm saying is that it doesn't matter what kind of GPS you're using. Set your destination(s) before you drive, and pull over if you need to adjust them. Telling drivers to do that is not "screw[ing] the poors", as you've suggested.
