I never use it
I think it`s a commie plot to maske us dumber
I`ve proven I`m a crappy spellor here.
but I`m pretty sure i`m better speller than most people under the age of 25 in the states.
gps also is a IQ killer
it makes people lose the ability to be familiar with thier surroundings.
people have accidents because they follows the gps instead of the traffic signs in front of them.
