My first GPS had a mode for scenic way or quickest way. My current GPS just has fastest or shortest way.
Every GPS maker needs to start to introduce new features. Number one, rest stop mode. Tell me where the closest state highway rest stop is, and if that is too far, a good bathroom break. Even more important, a "keep me out of the ghetto" mode.
And a scenic trip mode. Just don't allow people in RVs to have that mode!
