If you know your exit is coming up from memory why would you not already be in the correct lane? You’ve learned the route, you should be able to recognize when an exit is getting close. My concern with a gps is that it’s easy to get caught up in keeping track of traffic immediately around you, then get surprised when the gps says to take the next exit in half a mile because you didn’t know the road well enough to recognize the buildings/markers that it’s getting close, and you have gps so why bother looking at the actual signs.

If taking the next exit is an issue because it might take a while, then how does a gps figure out a shorter route? It’s literally the next exit, there is nowhere else to go before that exit, and if it’s taken a while to get there then the main road is almost certainly the fastest route back.

If I’m going somewhere for the first time in a while I will often check the gps before I leave to see if there’s construction or road closures because it can be helpful, but once I’ve confirmed there isn’t I close the gps and run off memory. One time a couple months ago I was driving down the freeway in the boonies and construction closed down a chunk of it. I started following the detour and got out of cell service range. Eventually there was another detour sign that directed my back toward the main road after the construction area. It was very helpful and also the norm when there is construction or events taking place, at least in my neck of the US.

I think gps can be a useful tool in the short term or to learn routes, but when I start talking about driving westbound on one of the largest freeways in the metro or point “that way” and my friend gives me a dull look because all they know is “turn left here” and “exit here,” it’s become a crutch. But I almost definitely put a higher value on knowing where I am and how to navigate than the average person does, and I don’t expect that to change, so it’s something I’ve come to (begrudgingly) accept.
