For the record, I use my phone. I use it mostly for traffic because I drive in a city every day. At any rate, I also like to see the entire route before I start, and I still find paper maps to be useful, especially on a long road trip. But when we travel, my husband always wants to drive (whatever, I don't care that much) and he prefers technology for anything and everything.
When we went to Ireland, I tried to help him navigate using a <gasp> paper map, but he would put our destination into his phone and off we would go. I, of course, would double check things on the map just in case. I would offer my suggestions but since neither one of us had ever been to Ireland, he wanted to trust the GPS. I could see it choosing odd routes but I figured as long as we got to where we were going, it would be fine. But I was still a bit peeved. Then one day, when we were almost to a highway it told him to turn right. It then proceeded to take us down one of those famous narrow Irish lanes, running parallel to the the highway the whole time. It meandered for a mile or two, getting narrower and narrower the further we went, causing us to have to pull over multiple times to let cars on the other side squeeze by us, and finally let us out on a larger road, and then the GPS took us to the highway. Now, I admit, I sat on my side chuckling to myself the whole time, and when we finally got out on the highway, I said "I am sure glad that I'm not the one who told you to go down *that* road".
Fun times with the GPS.
