I blame 4chan raiders. I can't say that wouldn't be lulzy, though.
If you're thinking about getting a GPS system, may I recommend a commercially available system that is built for your specific location (like the United States) as opposed to the Free Software Navit, using the Open Street Map system?
Here's why you want to avoid Navit and OSM at all costs: it tries to kill you.
Everything is fine up until it decides that the best route would be to use the expressway. Now, ignoring local traffic conditions, this would seem like the best route ... but the path taken is a tad heroic.
First, it instructs you to get on the wrong parkway, then make a SHARP RIGHT using your handbreak and get on the expressway using the offramp.

Second, it tells you to take a SHARP RIGHT off of the expressway overpass and on to the local street.
I hope you have good shocks.

Navit: for those of us who want to be able to shout "Yippie Kay Yay, Mother'efer!" in our daily lives.
have u tried the new tomtom software for the iphone? i want to try it out, but 100bucks is a bit steep. the Garmin Nuvi units are very good, i have one and it works perfectly, except when some destinations are directly off the highway, it tells u that u are there, but you are just passing it by on the highway... lame, that the only problem ive ever had with it though
Actually, you might be able to blame the Census Bureau for that -- The base data set for OSM's U.S. data is from the Census Bureau's public domain TIGER database, which unfortunately fails to include information on bridges and often declines to indicate one-way streets. There's a group of people working to fix this: http://wiki.openstreetmap.org/wiki/Tiger_fixup -- There has been much improvement in this area recently.
