Not sure if everyone knows this or not, reading all the anti-gps posts lately, I'm wagering a lot of people don't know this little tidbit.
You don't have to do what your gps tells you to do. If you don't like the looks of the road the gps wants you to turn onto, ignore the command. The gps isn't going to call in a drone strike on you for ignoring it.
If you're traveling to a destination 100s of miles away and the gps wants you to take the next exit off the interstate onto a dirt road leading into farm fields, just ignore it, you won't hurt its feelings.
