Open US GPS Data?

tobiasly writes "I read an article today about a map error on the popular Garmin GPS devices which often leads to truckers in a particular town becoming trapped. From my own experience, every electronic map I've ever seen (Google, Mapquest, my Mio GPS) has the layout of my neighborhood completely and frustratingly wrong. A quick search turned up only one open-source mapping project, but it's for New Zealand only. Why are there no comparable projects in the U.S. or elsewhere? Obviously such a project would need a good peer-review/moderation/trust system but I'd gladly put in the time necessary to drive around town with my GPS in "tracking" mode, then upload, tag, and verify my local data. Has anyone with more technical knowledge in maps and auto-routing looked more into this? Are there technical limitations to such a project? Should the government subsidize a project to create open, free, up-to-date electronic maps? Surely there is a public benefit available from such a project."

So why not move to somewhere with exquisitely accurate and detailed mapping? I hear that the nuclear reactors in Pyongyang and Iran have been mapped out quite well.

Make a U-Turn

The funniest thing about the Garmin is that is will tell you to make illegal U-Turns.
The story goes like this: My girlfriend got one for Christmas and we where going to test it by going to get grandmothers house. Halfway there my girlfriend went on autopilot, so to speak, because she's done this trip so many times. All the sudden we hear "Make a U-Turn... Recalculating" What the hell? Then we hear it again... The Garmin was telling us to perform illegal U-turns to work on its gps calculations.
I wonder if that would hold up "But officer. The GPS told me to!"

So it might ACTUALLY send you over the river and through the woods to Grandmother's House????

Around where I live (rural England), OSM seems only to have the medium-small roads on it that lead to pubs - make of that what you will!

Reading the post he's clearly from UK. Over in Europe, everything's better than in the US, even the problems.
