Who said I didn't have maps in the car? I said you were making that assumption (which isn't true in my case, for sure), so if this is an example of your accurate reading of anything, John, heaven help your route finding!
Bully for you and your photographic memory. Glad you can negotiate unknown territory in the dark. Hope I don't meet you on the road when you have to rapidly re-calculate your route because of external factors. All I have to do is touch the screen a couple of times and I'm still moving, still safe and still taking a sensible route. But you're proud of not relying on technology (apart from the car, of course, and email) so that's fine for you. I'm proud of using technology that helps me and not being too stuck up about it.
Different strokes, different folks.
