SO I’VE HAD THE GPS for a while, and it’s worked pretty well. Once or twice it got confused about whether a left turn was permitted or something, but overall the mapping is quite impressive, and it’s never really steered me wrong. As for my earlier worries that it would cause me to lose my sense of direction, well, not so much. Keeping it on in “map mode,” in fact, makes me aware of things in a new way. On the other hand, I was visiting somebody’s house the other night in a neighborhood that’s so new it’s not on the maps yet. Ordinarily I would have memorized the route back out, and I didn’t. That may have been GPS-induced laziness, or it may just have been . . . laziness.
