I guess I'm one of those who *needs* a GPS. ;-) It's great when I have to find a new route on the fly (I live near Washington DC which has the second worst traffic in the US). Just looking at a map before I leave isn't always enough. Traffic construction, accidents and just random slowdowns make driving a challenge and I want any advantage to shorten my drive.
I used to use the GPS on my smartphone but the screen was too small so when I finally purchased a new car (got rid of my 13yo SUV) I added a large screen in dash GPS and it's made my driving life a lot easier. Sure I could pack a ton of maps but this is far easier and I don't even have to pull over since my GPS is voice activated. Sure, having a GPS may be a bit over the top for some but I love it. Yes, I've used it to find food on the drive (and ATMs and gas stations).
