Most astute. I say that because it brings back a vivid memory of an observation my wife made about six years ago, the second time we were using our new personal navigation device to navigate in a large unfamiliar city. She observed that, while the GPS was a useful tool (because she didn't have to fight with the paper map and give me instructions), you still needed to pay attention to what was around you or you would have no better idea where you were with the GPS than without it.
(Anything that meshes with something my wife observes *must* be astute. I'm sure you see the reasoning. ;-)

We are rapidly heading away from that heavy human filtering by trained people for road maps. We (users) are the ones who do all of Google's filtering, now that they've dumped, first, Navteq and, later, TeleAtlas and gone with their own "mapping" efforts. They have teams who go out and drive around with the latest nav gear and cameras but after that it's pretty much automated. So we're the ones who filter and find and report the errors and provide the corrections. In many of the less populated areas of Canada Google's road maps went from not bad (Navteq) to awful (TeleAtlas) to horrid (Google's own efforts).
Here's a discussion thread that's something of a commentary on the [not so great] quality of a couple of current products, for various reasons. It's not the only place you'll see similar cautionary observations.
Since that thread began someone in Ketchikan, or some of the thousands of cruise ship customers who visit there each year, must have bitched loudly to Google. I see they've recalibrated their maps since I offered that example and they now have the roads nicely overlaying their images on the aerial photos.
