I was returning home from a long weekend at Myrtle Beach. While traveling down a state hwy, my 720 told me to turn off of the road. Checking it out quickly, it was clearly a detour since the route came back to the same hwy a mile or so further ahead. The detour was also in a different color. Since traffic was coming at a regular rate in the opposite direction, I ignored the detour. It was the right move. I suppose that was an old Map-Share correction. The detour was probably gone before it was posted.
Mapquest did this to me in 2005 while driving from Florida to New York. I had the directions printed on paper. Most of the way I'm supposed to be in 1-95 but many times it would have me get off of I-95, just go eventually merge with it and hour or 2 from now. This was around 2AM, and got me REALLY lost for about 4 hours. Mapquest had me cutting through towns. The next few times mapquest said to get off I-95 just to get back on it later again, I ignored them, and everything went well.
After just checking mapquest right now, they still want me to do the same. I guess these are "shortcuts" they want you to take, but it's so much easier just to stay on one damn interstate, considering you're going to be on it for at LEAST 700 miles anyways.
